Answer:
25
Step-by-step explanation:
to find slope, create the equation with what you have.
175 - y-intercept
25 - slope
X - hours spent painting
then plug it in with slope intercept form (y=mx+b)
y=25x+175
M is the slope in slope intercept form, and since 25 plugs in where M is, it is the slope.
Hope this helps!
(slope is always the number that can increase in a scenario, and y intercept is always a one time thing)
