Choose the system of equations that matches the following graph:

5x-y=7
2x-y=0

5x-y=7
2x+y=0

5x+y=-7
2x+y=0

5x+y=-7
2x-y=0

5x-y=7

2x+y=0

Step-by-step explanation:

Given system of equations:

5x-y=7   eq1

2x+y=0   eq2

By adding both equations we get:

7x = 7

Dividing both sides by 7 we get:

x = 1

Now putting value of x in eq2

2(1) + y = 0

2+ y = 0

y = -2

So the solution set is (1 , -2)

By looking at the given graph:

The intersection point of two lines is (1 , -2)

Hence proved that the given system of equations matches the graph.

i hope it will help you!

i will pick c put check it over to be sure

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
