Answer:

Graph A

Explanation:

We can draw a line by using only two points so we will find two points for each equation

Blue line: y = -1/2x + 3

For x = 0, y = 3

For y = 0, x = 6

Which is the blue line on graph A because its y-intercept (basically x=0) is (3,0) and its x-intercept(basically x=0) is (6,0)

Red line: y = x

For x = 1, y = 1

For x = 2, y = 2

Which is the red line on graph A because when x is 1 y is also 1 (see the graph) and when x is 2 y is also 2 (see the graph)

This should be enough because the other graph is completely different from graph A but here is the solution the system

y=-1/2x+3 | ×2

y=x

2y=-x+6

y=x

*Sum the equations*

2y+y=-x+6+x

3y=6

y=2

Now substitute y in y=x for example (it's easier) 2=x

So the point of interception is (2,2) as on graph A
