Question

Solve the system of equations by graphing and check your answer by substituting back into both the equations.

y = 2x + 3
3 = 4x + y

Answer 1

The solution is the point (0,3) where the two lines intersect.

Explanation:

Substitute x = 0 and y = 3

y = 2x + 3

3 = 2(0) + 3

3 = 3 checks

3 = 4x + y

3 = 4(0) + 3

3 = 3 checks
