Question

what is the slope of the line whose equation is:
a) x=-8
b) y=-9

Answer 1

if x = -8... that means no matter what y is... x is always -8.. so the "slope" is straight up and down.. which means it is undefined because rise/run = rise/0

Answer 2

i slope=infinity
ii slope=0

Answer 3

for y = -9 that means no mater what x is... y is always -9 so it's rise/run or 0/run which is zero

Answer 4

infinity for x and zero for y
