Question

Using the graphing function on your calculator, find the

solution to the system of equations shown below.
y-2x = -2
y-x = 1
O A. x = 3, y = 4
B. x = 4, y = 3
C. No solution
D. More than 1 solution

Answer 1

y - 2x = -2

y - x = 1

---------------

-x = -3, so x = 3 and y = 4

The correct answer is A.

To verify this answer, graph y = 2x - 2 and

y = x + 1 on the graphing calculator, and find the point where these two lines intersect. That point is (3, 4).
