all 3 are correct

Thank you, Reiny.

To check if an ordered pair is a solution to an equation, you need to substitute the values from the ordered pair into the equation and see if the equation is true.

Let's go through each equation and check if the given ordered pair is a solution:

11. Equation: y = 6x
Substituting the values from the ordered pair (3,16):
y = 6x
16 = 6(3)
16 = 18
Since 16 does not equal 18, the equation is not true. Therefore, the ordered pair (3,16) is not a solution.

13. Equation: y = -4x
Substituting the values from the ordered pair (-2,8):
y = -4x
8 = -4(-2)
8 = 8
Since 8 is equal to 8, the equation is true. Therefore, the ordered pair (-2,8) is a solution.

15. Equation: y = x - 3/4
Substituting the values from the ordered pair (2, 1 1/4):
y = x - 3/4
1 1/4 = 2 - 3/4
1 1/4 = 1 1/4
Since 1 1/4 is equal to 1 1/4, the equation is true. Therefore, the ordered pair (2,1 1/4) is a solution.

Based on the calculations, your answers are correct:
11. Not a solution
13. Has a solution
15. Has a solution
