Determine the slope m and y-intercept (if possible) of the linear equation. (If the slope is undefined, enter UNDEFINED. Enter NONE if there is no y-intercept.)

Question

y = 18
slope: m= 0
y-intercept: (x,y)=(0,18)
is my answers for slope and y-intercept correct?

describe it's graph:
a) The line is vertical and passes through (18, 0).
b) The line passes through (0, 1) and rises 1 unit for each horizontal increase of 18 units.
c) The line passes through (0, 18) and rises 1 unit for each horizontal increase of 18 units.
d) The line passes through (18, 0) and falls 18 units for each horizontal increase of 1 unit.
e) The line is horizontal and passes through (0, 18).

Answer 1

if the slope is zero, the line is horizontal, and all points on it have a y-coordinate of 18

Answer 2

for the describe the graph question, the answer would be c

Answer 3

no, the answer is E
I told you the line is horizontal!
geez! If you can't work it out, at least read what I write!
