First you must solve for "y" from the first equation:
Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":
ANSWER
x coordinates of the intersection points
EXPLANATION
The given system of equations is:
We want to use the graph of these functions to solve
The point of the intersection of the graph gives the solution to the simultaneous equation above.
Hence the x-coordinates of the intersection points gives the solution set of
The last choice is correct.
