Question

Find the point-slope form of the line that passes through (2,-1) and (1,-6)

Answer 1

First you need to find the slope by using the points: (2, -1) and (1, -6)
Formula for slope: y2-y1/x2-x1
-6 - (-1)/1-2
-6 +1 /-1
-5/-1
slope: 5
choose a set of points, either one is fine; you should end up with the same answer. I am going to choose, (2, -1) --> formula: y-y1=slope(x-x1)
y-(-1)=5(x-2)
