Question

Which of the following graphs shows the solution to the system of equations?

y = 5x – 1
y = x + 3

A.
B.
C.
D.

Answer 1

*Hint: When both equations are y =, you could solve them with substitution to get the value of x.

5x - 1 = x + 3
4x - 1 = 3
4x = 4
x = 1

Now, you would plug it in for x in order to solve for y.

y = x + 3
y = 1 + 3
y = 4

The answer would be (1, 4).
