Question

Is (0, -2) a solution of 2x - 5y = 10?

Answer 1

yes

Answer 2

it's also the y intercept

Answer 3

does 2(0)-5(-2)=10?

Answer 4

Do you know how to substitute values into an equation?

(0,-2) means that...
0 = the x value
-2 = the y value

So when you have 2x -5y = 10 this means

"2 times the x value minus... 5 times the y value ... equals 10"

So is that statement true, or is it false, given the values of x and y?
