Question

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.)
y = 18
slope: m=
y-intercept: (x,y)=

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).
