Question

Find the equation of the line passing through the points (-1,7) and

Answer 1

A)
slop intercept form is y=mx+b

To find m, it is (y2-y1)/(x2-x1) or (-8-7)/(2-(-1)) which then = -5

To find b, the y-intercept choose one of the points and solve for b using:
y=x(slope)+b
7= -1( -5)+b
7= 5+b
2=b (subtract 5 on both sides)

I hope this helped!
