Answer:

Option C is correct

(2, -3)

Step-by-step explanation:

Given the system of equation:

-3x+4y=-18                .....[1]

2x-y =7                   ......[2]

Multiply both sides by 4 in [2] we have;

8x-4y =28                 .....[3]

Add equation [1] and [3] we have;

5x = 10

Divide both sides by 5 we have;

x = 2

Substitute the value of x in [1] we have;

2(2)-y =7

⇒4-y=7

Subtract 4 from both sides we have;

-y = 3

⇒y =-3

Therefore,  the solution of the system of linear equations is, (2, -3)

What is the x-intercept for the following linear equation:
Alexandra [31]
The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis.  So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)
