Question

Yoooo, help on this question please? Picture is at the bottom.

Answer 1

plug x = -1 and y = -3 in every equation.

if the left side = right side, (x, y) is on the line/equation

if left side doesn't = right side (x, y) is not on the line

Answer 2

I don't get it o:

Answer 3

for C

5y = 12x - 3

plug in (x, y) = (-1, -3)

so

5(-3) = 12(-1) -3

-15 = -15

this is TRUE. so (-1, -3) is on the line: 5y = 12x -3



for B

-8y = 17x - 7

-8(-3) = 17(-1) - 7

24 = -24

this is NOT true. so (-1, -3) is not on this line. B is the answer.
