Question

Is the ordered pair (-8,1) a solution to the equation y=1/2x-3? Justify.

Answer 1

To find where the ordered pair is a solution to the equation, we must plug in the ordered pair:

      $y = \frac{1}{2} x -3\\1 = \frac{1}{2}(-8) - 3\\1 = -7$

So therefore (-8,1) isn't a solution to y= 1/2x -3

Hope that helps!
