Question

The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Find the slope and the y-intercept of the line.​

Answer 1

Answer:

Slope = 0.1 or 1/10

Y-int. = 15

Step-by-step explanation:

We have points (0,15), (3,45), (6,75), and (9,105).

slope is rise over run, or rise/run.

So, 9-3/105-45=6/60

now, simplify 6/60.

6/60=1/10 or 0.1

We already have the y-intercept, (0,15), because that's what intercepts the y-axis.
