Does the point (3,6) satisfy the equation y=4x-6?

Answer 1

Hi Jamie,

To answer this question, you would substitute the value of the x-coordinate (3) for the variable , x, and substitute the value of the y-coordinate (6) for the variable, y. Then complete the calculation and check if the solution is accurate.

y = 4x - 6

Substitute 3 for x and 6 for y and check to see if the result is true:

Does 6 = 4 • 3 - 6 ?

4 • 3 - 6 = 12- 6 = 6 YES

Since y = 6, then the point (3,6) is a valid solution for this equation.
