Which line has an undefined slope and goes through (5,-8)? a. y=5 b. y=-8 c. x=5 d. x=-8

Learn this...it helps
HOY = horizontal line, 0 slope, represented by x = a number
VUX = vertical line, undefined slope, represented by x = a number

undefined slope -- so its a vertical line
(5,-8)...remember, vertical lines are represented by x = a numberso we can say x = (now, what is the number for x in ur set of points ? it is 5...so ur equation is x = 5.  it does not matter what value y is, x is ALWAYS gonna be 5

Hey mate where is the graph
