Raj is deciding between two cell phone plans, A and B, which are both linear functions. The monthly charge for plan A according
to the number of minutes used is shown in the table. Monthly Charge for Plan A Minutes used, x Monthly charge ($), y 0 14.45 3 14.84 6 15.23 9 15.62 12 16.01 Plan B has the same monthly base charge as plan A, but it charges a different amount per minute used. If the total monthly charge for plan B is $22.10 when 45 minutes are used, what is the slope of the linear function that represents the cost of plan B?
Keisha is correct since all the points in quadrant one are positive. If the coordinates are interchanged, the x coordinate and the y coordinate will still both be positive so they will remain in quadrant 1
