Mauricio Briggs · Answer 1

Y = - x - 2

y = 2x + 4

-x-2=2x+4

x = - 6

y=-6-2

y=-8

The answer is (-6,-8).

Abraham Zamora · Answer 2

2x+4=y

In order to find the x intercept, y must equal 0.

X intercept:

2x+4=0

2x=-4

x=-2

In order to find the y intercept, x must equal 0.

Y intercept:

2 (0) + 4=y

4=y

(-2, 4)

x-y=2

x=2

-y=2

y=-2

(2,-2)
