Answer:

C) y = 2x + 7; y = 2x + 2

Step-by-step explanation:

The two lines are parallel and so will have the same slope.

From the graph, the slope of both lines are two.

Using slope intercept formula, y=mx+c, with m=2, we have y=2x+c

The blue line has a y-intercept of 2 so the equation is

[tex]y = 2x + 2[/tex]

The red line has a y-intercept of -7 so the equation is

[tex]y = 2x - 7[/tex]

Hence the system is

y=2x+2

y=2x-7

The correct answer is C
