Question

Dr. Ellison says that the equation y= -3x +7 has a solution of (2,13). Is Dr. Ellison right or wrong?

Answer 1

Dr. Ellison is wrong. When we substitute the value of x = 2 into the equation, we get y = -3(2) + 7 = 1, not 13. Therefore, the point (2, 13) does not satisfy the equation y = -3x + 7.
