Question

The graph of which equation is a line with undefined slope that passes through (5,1)?

f. y=1

g. y=5

h. x=1

j. x=5

Answer 1

j is correct: x=5

undefined slope means the line is vertical, with x= a constant. that rules out f and g, leaving only h and j

to go through (5, 1) requires x=5. (5,1) is the point with x=5, y=1
