Well first you need to find the slope. This is the equation:

y1-y2

——–<---this line means divide x1-x2 -5=x1 9=y1 -4=x2 7=y2 then you plug it in 9-7 ----- = -5+4 2 ---- this is your slope -1 Now you need to find the equation of the line. This is the equation: y-y1=M(x-x1) M is your slope. you choose on point to plug in. Lets take (-5,9) -5=x1 9=y1 Now plug it in. y-9=-2(x+5) use distributive prop. y-9=-2x-10 add 9 to each side y=-2x-1 THIS IS YOUR EQUATION>
