When you are given a point through which a line passes and the slope of that line, you can calculate the equation of that line. The general equation to solve this kind of equations is called as point-slope form. The point slope of a line passing through (a, b) with slope of m is (y - b) = m * (x - a). Now substituting the values in the above equation you can obtain the equation of the line in terms of x and y. In case you are given with two points first find the slope of the line which is the...
This video teaches us the method to draw the letter F in 3D. First draw F normally. Now double the outlines of the F on both sides of the outlines. Draw a line that is parallel and of the same length of the longer top arm of F. Join the ends of the line to the ends of the top arm by parallel lines. Color the parallelogram with a darker shade. Make a parallelogram by joining the ends of a line drawn parallel and equal to the smaller side of the rectangle of the top arm. Draw a vertical line an...
This video shows how to find the equation of the line perpendicular and parallel to a given line. The video starts off with an example, given the lines and the slopes (m). When 2 lines are parallel to each other, they have the same slope. When 2 lines are perpendicular to each other, the slopes multiplied together will give -1. Knowing these rules, the tutorial maker provides an example with numbers. He then leads each step of the process. Each step is written out in either black, red, blue o...
Fine Homebuilding with Jim Anderson demonstrates how to cut floor joists to length. Inspect the rim line to know where to set the joists. Set the joists to the layout on the rim line using a two man team. Tap a nail into the joist to keep it from moving around. Instead of standing the joists up to square them, cut them on both ends. Line the chalk line up with the rim line and snap the line across the joists to mark them. This will simultaneously measure and square them. Finally, line the joi...
This video shows the way to name a line segment. A line segment begins and ends with an end point. We can name a line segment by naming the two end points of the line segment. The example shown in the video shows a line segment that ends with points named 'A' and 'C'. So, we can name this line segment as segment 'AC'. This can also be named as segment 'CA'. The example shown consists of a point 'B' in between 'A' or 'B'. We cannot name the line segment as segment 'AB' or 'BA' and segment 'BC'...
This videos explains how one can easily find the parallel line to a given mathematical equation. He starts by explaining what it means for two lines to be parallel mathematically speaking. Defining two lines, then comparing the slope of both lines you can mathematically determine that they are in fact parallel. He then moves to common math problems found on tests where you are given a point and a linear equation. He then forms a T-table with one column being line one and line two and illustra...
This is the video about how to find the equation of a tangent line. As you may recall, a line which is tangent to a curve at a point a, must have the same slope as the curve. Therefore, the slope of the tangent is m = lim f(a + h) - f(a) h-->0 h Since the slope equation of the tangent line is exactly the same as the derivative definition, an easier way to find the tangent line is to differentiate using the rules on the function f. For example, Find the slope of a line tangent to the function ...

A good starting point is the middle C on the keyboard. For a piano, you have horizontal lines in two sets on the sheet of paper. These lines are called "staffs" and the vertical lines are the "bar lines". The sections are called "measures". The top of those staffs is all the notes above the middle c. The bottom is all the notes below m...
In this tutorial, we learn how to bisect a line segment. First, you need to adjust your compass so the distance from the sharp part and the drawing part is the size of the line. Then, put the sharp part on one side and draw your arc with the pencil. Do this on both sides of the line so your image shows two arcs that intersect each other. Since you have these two intersecting lines, you can draw a line between these to show where the middle of the line would be. Use a ruler to draw this straig...

You want your shadow to be realistic so you want to think about where you light source will be. To paint on shadows lines, focus on where the light source is coming from and darke...
A good place to start when you want to learn how to find a midpoint of a line is a circle. Take the diameter of a circle, for instance if the coordinates of the starting point are (1,6) and the coordinates for the ending point are (11,6). The midpoint of a line is the exact central point where a line through these two points would meet. Now the value of y is a constant one as the line runs parallel to the x-axis, the value of x changes by 10, the half of which is 5, this is not the midpoint t...
