What’s slope anyway? Well, kind of intuitively, it’s just a way to measure how tilted a line is. We could say “oh, this one is kinda tilted just a little bit, and this other one is titled a lot, but in the other direction, and this one is tilted more than that one.” But that’s a whole lot of words and ain’t nobody got time for that. We want to attach a number to measure how tilted a line is, so we use the formula for slope:
Where all the x’s and y’s are coordinates of two particular points: (x1,y1) and (x2,y2). Here’s the trick you might not know though…
IT DOESN’T MATTER WHICH TWO POINTS YOU USE.
That’s the beauty of slope, if they give you a graph and ask you to find the slope, you can pick any two points on the line, and those can be your (x1,y1) and (x2,y2). So pick a couple that make your life easy. Pick points that are definitely whole numbers!
That’s all for now Brightstormers, beware the slippery slope!
