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= 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).
if the slope is zero, the line is horizontal, and all points on it have a y-coordinate of 18
for the describe the graph question, the answer would be c
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!
Your answers for the slope and y-intercept are incorrect.
For the equation y = 18, the slope is actually undefined (UNDEFINED) because the equation represents a horizontal line. A horizontal line has the same y-value (in this case, y = 18) for all x-values.
Since the slope is undefined, there is no y-intercept (NONE). The y-intercept refers to the point where the line crosses the y-axis, but in this case, the line doesn't intersect the y-axis at all because it is parallel to it.
To describe the graph of the equation y = 18:
e) The line is horizontal and passes through (0, 18).
This means that the line is a straight line that is parallel to the x-axis and intersects the y-axis at the point (0, 18).
