Answer:
y-intercept = -5
Explanation:
Slope-intercept form of a linear equation:

(where
is the slope and
is the y-intercept)
In order to find the y-intercept of the given line, rearrange so that it is in slope-intercept form:
Given equation:

Add y to both sides:


Subtract 5 from both sides:


In slope-intercept form:

Therefore,
- slope (m) = 18
- y-intercept (b) = -5
