Question

verify that (-2,6) is a solution of y=-x+4

Answer 1

substitute the x and y values into the equation. if you get an identity or a true statement (and you will in this case),then (-2, 6) is a solution

Answer 2

so my answer is 2 , so it is not a solution.

Answer 3

what do you mean 2? (-2, 6) actually *is* a solution.

(6) = -(-2) + 4

6 = 6
