Question

is (2, -3) a solution of y = x + 5? I got x = -8. Correct???

Answer 1

its not a solution

Answer 2

you are correct. (2, -3) is not a solution

Answer 3

no the answer is 7

Answer 4

x = -8 is not the right way to think of it. Plug x and y values into the equation.

You get:
-3 = 2+5, which is never true. So, not a solution.

Answer 5

so its a yes or no question?

Answer 6

Yes.

Answer 7

ok thank you

Answer 8

GT, I don't see a problem if she only plugged in y value. if she didn't get 2, it's obvious that it's not a solution.

Answer 9

For a point to be a solution to an equation like the one you have, it must satisfy the equation. For example, if you had a point (2,7), it would satisfy the equation when you plug in as follows

7 = 2 + 5, which is clearly true.

Answer 10

slaaibak - agree. many ways to come at math problems.
