Is (3, 0) a solution to the equation y = -3x?

Question

help me understand this.please.

Answer 1

The question is asking if the point (3,0) satisfies the equation y = -3x

If a point satisfies the equation, you replace the x and y with the x and y coordinates of the point and the equation will be true.

In this case, since the x coordinate of the point is 3 and the y coordinate is 0, we would substitute 3 for the x and 0 for the y in the equation

y = -3x

(substituting the point)

0 = -3 * 3

0 = -9

Since 0 ≠ -9, the point is not a solution
