Question

Choose the system of equations that matches the following graph:

Answer 1

Answer:

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.
