Question

write a word problem that results in a slope intercept equation. it can be proportional or non-proportional.

Explanation:

Created a non-proportional word problem (has a starting value, so y-intercept ≠ 0) that translates to a slope-intercept form equation $y=mx+b$, where $m$ is the rate of change (slope) and $b$ is the initial value (y-intercept).

Answer:

Word Problem:
A bike rental shop charges a $10 initial fee plus $8 for every hour you rent a bike. Write an equation that represents the total cost $y$ of renting a bike for $x$ hours, and identify the slope and y-intercept.

(The corresponding slope-intercept equation is $y=8x+10$, where the slope is 8 and the y-intercept is 10)
