Slope of line j;
m=

m=

m=

Parallel lines have equal gradients;
So,
y=mx+c
y=5/3x+c
Replacing for x and y;
-1=5/3(15)+c
-1=25+c
c=-26
y=
The Slope represents the difference of the selling price and the product cost: m=35-15=20 and the Y-intercept represents the one time cost of the editing books: b=-1,050
