Question

is (-2,-6) a solution to the equation y=3x

Answer 1

Why not substitute the values and see?

Answer 2

i tries i dont get it i am frustrated with it

Answer 3

You have the relationship y = 3x
You are given x = -2, substitute: y = 3(-2)
You are given y = -6, substitute: -6 = 3(-2)

Is that last equation true or not?

Answer 4

yes i think so

Answer 5

3(-2) = -6 Yes it is.

The challenge, I think, is to recognize that "(-2,-6)" means x = -2 and y = -6.
