Question

HELLLLPPPPPP!!!!!!!!!!!! THIS WAS DUE LAST WEEK!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

1. turn it into standard form:

first equation:

y = x − 4

y - x = -4

second equation:

y = 3x + 4

y - 3x = 4

2. multiply the first equation by -3 and then add both equations in order to remove x.

-3y +3x = 12

+ y - 3x = 4

-2y = 16

y = -8

3. With y, plug it in the first equation.

-8 = x -4

x = -4

Your intercept is (-4, -8)

The answer is (−4, −8), because the point satisfies both equations

Answer 2

The answer is.. -4, -8.

Hope this helps!!
