Question

Which one-variable linear equation can be represented by this graph?

A.
x = 3
B.
3 – 3x = 3
C.
3x – 3 = 3
D.
y = 3x

Answer 1

You have 2 graphs:
y = 3 (the flat one)
y = 3x - 3 (the sloped one)

Is there a way to combine those two equations to get rid of the variable y?

Answer 2

Yeah right?

Answer 3

you subtract y from both sides of the equation right?

Answer 4

C
