Question

What is the equation in point slope form of the line that goes through the points (-4,-2) and(-6,16)

Answer 1

y+2=-9(x+4)

Explanation:

Point Slope Form: y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

m=(y2-y1)/(x2-x1)=(16-(-2))/(-6-(-4))=(16+2)/(-6+4)=18/-2=-9

So the slope is -9,

y-(-2)=-9(x-(-4))

y+2=-9(x+4)
