1. (12 points) Goods $x_1$ and $x_2$ sell at prices $p_1$ and $p_2$, respectively, and a consumer has income $m$ to spend on the two goods. For each of the following scenarios, find an algebraic expression for the consumer's budget line and illustrate it in a diagram, indicating the values of the slope and intercepts.
a. (4 points) The consumer can exactly afford the $(x_1, x_2)$ bundle $(10,2)$, and $p_1 = 3$ and $p_2 = 5$.
b. (4 points) The consumer can exactly afford the $(x_1, x_2)$ bundle $(10,2)$, and $p_1 = 3$ and $m = 60$.
c. (4 points) The consumer can exactly afford both of the following $(x_1, x_2)$ bundles: $(10,2)$ and $(6,4)$.
