Question

Ok I give up. I just need the answers please to get by this section. (-2, -1) & (-9, -4) in slope intercept form.

Answer 1

m = (y2 - y1)/(x2 - x1)
so, (-4 +1)/(-9 + 2)
you get
-3/-7 = 3/7
so you have ur slope intercept formula y = mx + b
you got ur m = 3/7
y = (3/7)x + b
now choose any of the 2 points (doesnt matter which), ill choose (-2, -1)
plug and chug
-1 = (3/7)(-2) + b solve for b
-1/7 = b
so your answer is
y = (3/7)x -1/7
