Question

Solve the system of equations y = x + 5 and y = 5x - 11 using a graphical method.

A) (4, 9)
B) (9, 14)
C) (9, 4)
D) (14, 9)

Answer 1

You can use substitution for this.

x+5 = 5x -11

Combine like terms

16=4x

Divide 4 on both sides to isolate the x

x=4

Plug x=4 to one of the equations

y= 4 +5

Combine like terms

y=9

So the answer is A. (4,9)

I hope this helps you out a bunch hun :)
