Question

Write an equation in point-slope form of (-3,5) (9,1)

Answer 1

To find the slope:

Y(2)- Y(1) 1-5 -4= 1

X(2)-X(1) 9+3 12= -3

Slope = -1/3

To find y-intercept, substitute:

Y=Mx+B

1= -1/3(9) + B

1= -3 + B

4= B

Convert to point-slope form:

Y=-1/3x+4

+ 1/3x

Your answer is:

1/3x+y=4
