Question

For each ordered pair, determine whether it is a solution to y=-7

(-1,-7)
(-7,0)
(9,5)
(4,-7)

Answer 1

To determine whether an ordered pair is a solution to the equation y = -7, we need to check if the y-coordinate of the ordered pair is -7.

For the given ordered pairs:

(-1, -7):
The y-coordinate is -7, so it is a solution to y = -7.

(-7, 0):
The y-coordinate is 0, not -7, so it is not a solution to y = -7.

(9, 5):
The y-coordinate is 5, not -7, so it is not a solution to y = -7.

(4, -7):
The y-coordinate is -7, so it is a solution to y = -7.

Therefore, the ordered pairs (1,-7) and (4,-7) are solutions to the equation y = -7.
