Question

Is (-4, 10) a solution to the equation 10 - 5x=y

Answer 1

Plug in -4 into x and 10into y
10+20=10
30 does not equal 10
The answer is no

Answer 2

plug in the points into the equation.

10 - 5(-4) = 10

10 - (-20) = 10

10 + 20 = 10

30 = 10

so there isn't a solution.

hope that helps, God bless!
