write an equation of the line passing through the pair of points or state that the slope is undefined. (-3,5) and (3,-7)

AveGali [126]

Step-by-step explanation:

equation of a line = y-y1=m(x-x1)

but we have to find the slope

so slope=y2-y1 = -7-5

x2-x1. 3--3

-12

-2

1. =-2

y-5=-2(x-3)

y-5=-2x+6

y=-2x+6-5

y=2x+1
