The point-slope form:

$y-y_1=m(x-x_1)$

We have a slope m = 4 and the point (-3, -1). Substitute:

$y-(-1)=4(x-(-3))\\\\\boxed{y+1=4(x+3)}\to\boxed{b}$

Answer:

Step-by-step explanation:

(a²-2ab+b²)=(a-b)²

a²+2ab+b²=(a+b)²

i solve b and d

(b)

9x²-36x+36=0

(3x)²+2×3x×-6+(-6)²=(3x-6)²

(d)

a²-b²=(a+b)(a-b)
