Which equations match the graph?

f(x)=2x+3 \textrm{ and } g(x)=\frac{2}{3}(\frac{4}{5}x)+3

f(x)=\frac{1}{2}x+3 \textrm{ and } g(x)=\frac{2}{3}(\frac{4}{5}x)+3

f(x)=2x+3 \textrm{ and } g(x)=\frac{2}{3}(-\frac{5}{4}x)+3

f(x)=\frac{1}{2}x+3 \textrm{ and } g(x)=\frac{2}{3}(-\frac{5}{4}x)+3

An app development company makes a new utility that sells for $2 per download. Counting all their expenses (paying worker wages, rent on their office, etc.), they spent $9,800 bringing the product to market. Their total net profits are modeled by the linear function p_{_{1}}(s)=2s-9800, where the input s is how many copies of the app they sell. When there is a security scare, they pay a special data privacy expert $4,500 to make sure they've followed industry best-practices to protect customer information.
A) Write an equation for a new function p_{_{2}}(s) that takes into account the additional $4,500 cost.
B) Describe the transformation from p_{_{1}}(s) to p_{_{2}}(s).
