Question

I do not understand how to find x on a graph when there is no equation. I have the possible answers: a) x= -3, b) x=-1, c) x=5, d) x=1

It asks me to find the value of x when y is 5; however, the graph I have has a line (0,2) on the y axis and on the x axis it looks like it could be (o, 3/4)

Answer 1

x = -3 is an equation; it has an equal sign. It would be graphed as a vertical line at x = -3. All the rest (b, c, d) would be vertical lines at their values. Whichever equation you are dealing with, x has the same value regardless of the value of y.
