Question

Look at the graph of the system of equations below. (Image Below)

How can you prove that the point of intersection of the lines on the graph is the solution to both equations?

A. Substitute 1 as the y value in each of the equations and solve for x

B. Substitute 7 as the y value in each of the equations and solve for x

C. Substitute 3 as the x value in each of the equations and solve for y

D. Substitute 6 as the x value in each of the equations and solve for y

Answer 1

Answer:

option c is correct

substitute 3 in both and solve for y

if both give same value of y then it is solution of both equation.
