Answer:
Step-by-step explanation:
so we use the equation y2-y1=m(x2-x1)
let's say (-3,1) is point 1 and (-5,8) is point 2
we plug in what we know
8-1=m(-5-(-3))
subtracting a negative is the same as adding so -5 - (-3) = -2
7=-2m
divide both sides by -2
-7/2=m
-3.5=m
so slope intercept form is y=mx+b
we know the slope (m) but we still need the "b" which is the y-intercept.
so you pick whichever point you want (I'm going to chose point 1 but it doesn't matter) and plug it in
1=-3.5(-3)+b
1=10.5+b
-9.5=b
so the equation would be y=-3.5x-9.5
