Finding Line Using Only Slope - Point Slope Form

3 years ago

Hi everyone! For this video, I will tell you that all you need to know is the formula for slope.

m = (y2-y1)/(x2-x1)

From this formula, you actually can find out the other two formulas: the point slope form and the slope intercept form. If you could only memorize one formula to find lines with slope, you should remember the slope formula. At the beginning of the video, I explain how to get from m = (y2-y1)/(x2-x1) to y-y1 = m(x-x1) and y = mx + b. For the second part of the video, I go over a few examples on how to find the line in point slope form when given the slope and a point that the line passes.

Let me know in the comments below if you have any questions. Thanks for watching!
