Question

How do I find the missing values that solve this equation. y = 3x (0, ____) (-1,____) (7,____)

Answer 1

ok so if y = 0
then 0 = 3x

Answer 2

hence for y = 0 , x = 0 right ?

Answer 3

Yes.

Answer 4

ok so if y = -1 can u tell me what will be x ?

-1 = 3x ... x =?

Answer 5

would it be 1?

Answer 6

divide both sides by 3 ..

\[\frac{-1}{3}=\frac{3x}{3}\]
\[\frac{-1}{3}=\frac{\cancel{3}x}{\cancel{3}}\]

Answer 7

That gives me 3 right?
