Step-by-step explanation:
The y-intercept is where x is equal to 0, and the x-intercept is where y is equal to 0, so:

The equation is written in slope-intercept form:

m is the slope and b is the y-intercept, so the y-intercept is -18.
Now set the value of y to 0 to find the intercept of x:

Solve for x. Add 18 to both sides:

Divide both sides by 8:

The x -intercept is
