Question

y = 4
Complete these ordered pairs for this equation
(0, ) , (-1 , ) , (2, )

Answer 1

y = 4 is a horizontal line at the same height of 4 units above the x-axis.
No matter what point you choose on this horizontal line, y will ALWAYS be 4.
So the y-coordinate will always be 4 for this line no matter what the x-coordinate is.
