Tell whether the ordered pair is a solution of the equation

y=5x; (15,-3)

This ordered pair is NOT a solution of the equation.

Step-by-step explanation:

First, it is important to note that ordered pairs consist of (x, y) so in this case

x = 15 and y = - 3. And that any variable directly next to a number calls for multiplication. So, plugging in the variables the equation would look like

"-3 = 5 x 15"

To see if 5 x 15 = - 3 we will multiply them. 5 x 15 actually equals 75 not - 3. So we know this ordered pair is NOT the solution for the problem.
