Question

What is the equation for the following graph? a. y=-4 b. y=4 c. x=4 d. x=-4

Answer 1

Answer:

x=4

Step-by-step explanation:

Consider the coordinate pair (4,y)

We observe that,

y can take any real values to lie on the graph of the equation.

As y really isn't a constant, we exclude it and take the equation as x=4
