The graph represents the cost of a subscription to a newspaper. A coordinate plane showing Ferry Ride Cost with Number of Persons on the x-axis and Total Cost in dollars on the y-axis with a line passing through points at (1, 2) and (5, 8). What is the constant of variation for the subscription cost based on the number of weeks?

The constant of variation for the subscription cost based on the number of weeks is 4

Step-by-step explanation:

The equation of a line in intercept form is given by:

y = mx + c

Where c is the intercept on the y axis and m is the slope of the line which is constant.

In this problem, we are asked to  find the constant of variation, this can be determined from the slope because the slope is the  constant of variation.

The  Ferry Ride Cost with Number of Persons on the x-axis and Total Cost in dollars on the y-axis. The equation of a line passing through two points is given by:

The points are (1, 2) and (5, 8), therefore using:

Comparing y = 4x -2 and y = mx + c, m = slope = 4

The constant of variation for the subscription cost based on the number of weeks is 4
