a simple question but i need help

for which eqn is the graph of a line w/ undefined slope that passes through (5, 1)

a. y=1

b. 5x=y

c. x=5y

d. x=5

and can you show me how you did the problem. thanks

(5,1) is the point on the graph where x = 5 and y = 1.

Plug in x = 5 to each equation and see which one gives you y = 1. Note that one of the equations does not even require a value of x to get determine y.
