Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" the y-intercept.
Since the given line has a y-intercept at (0,-15), then:
The formula for calculate the slope is:
Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:
Substituting values into , we get that the equation of the line in Slope-Intercept form is:
