a simple question but i need help
for which eqn is the graph of a line w/ undefined slope that passes through (5, 1)
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.
