For each ordered pair, determine whether it is a solution to y=-5x+2.

There are two ways to do this.

The first is you plug in the x-value from the point in the table and see if that gives you the y-value from the same point.

For example, your first point is (5,49), so plug in x=5:

   y = -5(5)+2 = -25+2 = -23

Since that's not the y-value in (5,49), then (5,49) is not a solution for the equation.

The other option is you plug in both the x-value and the y-value to see if you get a true statement.  (A solution will make the equaiton a true statement.)

For example, the first point is (5,49), so you'd plug in x=5 and y=49:

    49 = -5(5)+2

    49 = -25 + 2

    49 = -23

Since that's not true, (5,49) is not a solution.

You'll notice you're basically doing the same thing, it's just whether you plug in one value or both and that's your choice.

found it xd it ok yt
