Question

What is the intersection of these two lines 2x+4=y x-y=2

Answer 1

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)

Answer 2

Y= -x -2
y= 2x +4
-x-2=2x+4
x= -6
y=-6-2
y=-8

The answer is (-6,-8).
