Question

Does the point (6, 4) satisfy the equation y = -8x?

Answer 1

No.
x = 6, y = 4
4 = -8(6)
4 = -48
4 is not equal to -48

Answer 2

No

Explanation:

To determine if the point is a solution to the equation.

Substitute x = 6 into the right side of the equation and if the value equals the y- coordinate of the point then it is a solution.

y = - 8 × 6 = - 48 ≠ 4

Thus (6, 4 ) is not a solution of the equation
