Tell me easy way i can solve for the answer

y+21 = -4(x-7)

Step-by-step 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

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

true. i hope this ! go answer some of my newest
