Is (1, -4) a solution for the equation y = -2x?

My answer is 1 = 2 (-4)
1 = -8 No it isn't

Doesn't (1,-4) mean x = 1 and y = -4? So

-4 = -2(1) and I agree it isn't.

You are right the first position in the ordered pair is always the value.

Thank you

To check if the point (1, -4) is a solution for the equation y = -2x, you need to substitute the values of x and y into the equation and see if it satisfies the equation.

Here's how you can do it:

1. Start with the equation y = -2x.
2. Substitute the x-value of the point (1, -4) into the equation. Replace x with 1: y = -2(1).
3. Simplify the expression: y = -2.
4. Compare the result with the given y-value of the point, which is -4. Is -2 equal to -4? No, it isn't.

Therefore, the point (1, -4) is not a solution for the equation y = -2x.
