3. a friend gives you two baseball cards for your birthday. afterward, you
begin collecting them. you buy the same number of cards once each
week. the equation y = 4x + 2 describes the number of cards, y, you
have after x weeks. (example 2)
a. find and interpret the slope and the y-intercept of the line that
represents this situation. graph y = 4x + 2. include axis labels.
b. discuss which points on the line do not make sense in this situation.
then plot three more points on the line that do make sense.
