Linear functions r and s are graphed on the same coordinate grid. The y-intercept of the graph of r is 7 units above the y-intercept of the graph of s. Which pair of functions could be used to create the graphs of r and s?

• r(x) = 7x and s(x) = x

• r(x) = x − 7 and s(x) = x

• r(x) = x + 7 and s(x) = x

• r(x) = −7x and s(x) = x

A publisher sells puzzle books. The publisher has fixed costs of $450, and each puzzle book costs an additional $0.50 to make. The publisher sells each book for $1.50.
