2 + .25x
The 2 is the fixed rental for the book
.25x is the late fee per day where .25 is the charge per day and x is the number of days

For a line with slope m that passes through a point

, the point-slope form equation is the following.

We have a given slope of 4 and a given point of (7,5). Now, plug in the values.

That is the
point-slope form of the line. Now, let's change this into slope-intercept form. Slope-intercept form looks like the following:

Where m is the slope and b is the y-intercept. Let's do some algebra on our point-slop form equation to change it into slope-intercept form.

This was our equation. Let's use the distributive property on 4(x-7).

Now, add 5 to both sides of the equation

This the
slope-intercept form of the line. Thus, we have solved for both the point-slope form and the slope-intercept form. Hope this helps! :)
