Question

Please tell me easy way I can solve for the answer

Answer 1

y+21 = -4(x-7)

Explanation:

well first you need to find slope what is y2-y1 over x2-x1

23-(-21) ----> 23+21 = 44

-4 - 7 ---> -4 + -7 = -11

so it 44/-11 = -4 is the slope

now choose one pair of points like 7 , -21 and plug them in

y-y1 = m(slope)(x-x1)

so it be y+21 = -4(x-7)

also remember two negatives = a postitive
