To find out how many more comic books Meg has than Sara after 2 months, we need to substitute x = 2 into the equation for Meg's comic books and then subtract the equation for Sara's comic books from it.
For Meg after 2 months:
y = mx + c
y = 8/4 * 2 + 12
y = 4 + 12
y = 16
For Sara after 2 months:
y = 2x + 15
y = 2 * 2 + 15
y = 4 + 15
y = 19
To find how many more comic books Meg has than Sara, we subtract Sara's total from Meg's total:
Meg - Sara = 16 - 19
Meg - Sara = -3
Therefore, after 2 months, Meg has 3 fewer comic books than Sara.
Sara and Meg buy an equal number of comic books every month. The following equation shows the number of comic books, y, that Sara has after x months:
y = 2x + 15
The following graph shows the number of comic books, y, that Meg has after x months:
Graph shows Months on x axis and Number of Comic Books on y axis. The scale on x axis is shown from 0 to 5 at increments of 1. The scale on y axis is shown from 0 to 28 at increments of 4. The title of the graph is Megs Comic Books. A straight line is shown which joins the ordered pair 0, 12 and 4, 28
