Question

Dr.Ellison says that the equation y=-3x +7 has a solution of (3,-2). Is Dr.Ellison right or wrong?

Answer 1

To determine if Dr. Ellison is right or wrong, we need to substitute the given solution (3, -2) into the equation y = -3x + 7.

Substituting x = 3 and y = -2 into the equation, we get:
-2 = -3(3) + 7

Simplifying the right side of the equation:
-2 = -9 + 7
-2 = -2

Since both sides of the equation are equal, we can conclude that Dr. Ellison is correct. The equation y = -3x + 7 indeed has a solution of (3, -2).
