The cost of tickets to the amusement parks is $19.50 for 1 ticket and $78 for 4 tickets

Question

Tell whether the slppe is a line that models each situation is positive, negative, or undefined. Then find the slop

Answer 1

Step1. Graph the points where the number of tickets will go in the x axis and the price is on the y axis in the Cartesian coordinate hyperplane, Cartesian coordinate system or in the rectangular coordinate plane which is a 2 dimensional plane or 2 dimensional hyperplane.

Step 2. Look at the graph if the slope increases, decreases, or is undefined with respect to the number of tickets purchased and according to the model of the graph the slope will be increasing in the graph. So therefore each situation is positive.

Step 3. Use the slope formula m=(y2-y1)/(x2-x1) which is m= (78-19.50)/(4-1) which is equivalent to m=19.50, which m is the slope. So the slope is 19.50.
