* Question 5
Paige claims that the solution to the system of linear equations y = 2x -1 and -12x + 3y = 9 is (-2, -5).
Select all methods that could be used to prove Paige's claim.
A
Solve 3 + 4x = 2x-1 for x and substitute into y = 2x-1 to find the value of y.
Graph each linear equation and show that the intersection of the lines is (-2,-5).
Solve -12x + 3(2x - 1) = 9 for x and substitute into y = 2x -1 to find the value of y.
D.
Substitute -5 for x and -2 for y into both equations and show that the equations are true.
