Question

1). y=x;(2,3) Tell whether the ordered pair is a solution of the equation. 2) Y=3x -2; (1,1)

Answer 1

1) no, (2,3) is not a solution of y=x.

2) yes, (1,1) is a solution of y=3x-2

Explanation:

When you have a point, the first number is x and the second number is y, (x,y).

If you substitute the numbers in for x and y, you will get a true statement if the point is a solution.

Look at y = x, put in 2 for x and 3 for y.

You get 3 = 2, that's false. So (2,3) is NOT a solution of y = x.

Then consider

y = 3x - 2; fill in 1 for x and 1 for y

You get

1 = 3(1) - 2

1 = 1 , a true statement. So (1,1) IS a solution.

Answer 2

(2, 3) is not an ordered pair for y = 3x - 2.

Explanation:

(2,3)

y = 3x - 2

3 = 3(2) - 2

3 = 6 - 2

3 = 4

This means that (2, 3) is not an ordered pair for y = 3x - 2.

Hope this helps!
