This formula is for finding the distance between a point and a line, but, as you said, it's pretty complicated. In the formula, the line is represented as Ax+By+C=0, instead of y=mx+b. You can learn more about this representation of a line in this video:

Copy from Kim Seidel's answer: Find the change in Y and change in X between that 2 points that you have. Your point b will be on the opposite side of the midpoint from point a. And it will have the same change in Y and change in X. For example: If a = (2,5) and the midpoint = (-1,3): Change in Y = 5-3 = 2.Course challenge.

And then we can get another angle. So let's try to measure this one right over here. So once again, place the center of the protractor at the center, at the vertex, of our angle. We can place the 0 degree, the base of the protractor, at this side of the angle. So let's just rotate it a little bit, maybe one more time.Test your understanding of Volume and surface area with these % (num)s questions. Start test. Volume and surface area help us measure the size of 3D objects. We’ll start with the volume and surface area of rectangular prisms. From there, we’ll tackle trickier objects, such as cones and spheres. ….
