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.
