If (-7,43) and (4,-12) are two anchor points on the trend line, then find the equation of the line

Romashka [77]

Slope, found using the points is -55/11 = -5
We use that for the equation y=mx+b where m=-5. Since we also know one of the points, we can plug that in and find b
-12=-5(4)+b
-12=-20+b
8=b

So the equation of the line is y=-5x+8
