Is (-7, 7) a solution to y = -x?

Answer 1

We want to know if the point lies on the line. So let's check the point by plugging it in. If y=-x and our x-coordinate is -7 and our y-coordinate is 7, then for it to be a solution, it must satisfy the equation.

So: 7=-(-7) and the double negative makes a positive, so we have 7=7 which is true. Hence, (-7,7) is a solution to y=-x.

Hope this helps!

Answer 2

Well, x=-7 is a solution to the equation and the point on the graph where x=-7 is (-7,7)
