Question

Is the coordinate pair: (2,50), a solution to the equation y=20x + 10? Explain.​

Answer 1

Yes, it is.

Explanation:

If you substitute the point (2, 50) into the equation, you get 50 = 40 + 10. This is a valid statement, so the point is a solution to the equation.

Answer 2

Answer: It is a solution.

Explanation:

We will substitute the coordinate pair values into the equation to answer this question. Coordinate points are written as (x, y) so we will substitute them as such. If the equation is equal and correct, it's a solution.

y = 20x + 10

50 = 20(2) + 10

50 = 40 + 10

50 = 50 ✓

This is a solution because the values substituted into the original equation make the equation true.
