When solving the following system by graphing, what will the solution be?


y = 2x - 1

-6x - 3y = 3

There is one solution to this system of equations and it is located at the point where the two lines intersect.

There is no solution because the lines will never intersect

There is no solution because the lines will intersect somewhere off the graph

There are infinitely many solutions because the lines are the same line

When using substitution to solve this system of equations, what is the result of the first step?

y = -2x +8

3x - 2y = 19

(3x - 2y) = -2x + 8

3x - 2(-2x + 8) = 19

3(-2x + 8) -2y = 19

3x -2(-2x) = 19
