Question

1 What is the cost to get into a Green Cab?

2 How much does it cost per mile for a Green Cab?
3 What is the equation, in slope-intercept form, that relates the cost compared to the miles traveled for a Green Cab?

Answer 1

1. $5

2. $1 per mile

3.y=x+5

Explanation:

1. If you look at the graph you can see that the cost for 0 miles with the Green Cab is $5

2.If you look at the graph, for each mile traveled, the cost is $1

3. Since for each increase 1 increase in x, y increases by the same amount, the slope is 1

y=mx+b is the slope intercept form

m=slope

b=y intercept

since we know the slope is 1 we can put it in

y=1x+b

=y=x+b

to find the y intercept we can look at the graph and see what y equals when x is 0.

the y intercept is (0,5)

we can put that in so the equation in slope intercept form is

y=x+5
