Question

(This looks basic, but I need help) In the table below, x represents miles traveled and y represents the cost to travel by train.
Table

x y
2 8.50
5 15.25
8 22.00
12 31.00

What is the y-intercept of this function?

a. 2.25
b. 4.00
c. 6.50
d. 17.13

Answer 1

The answer is B, friendo.

Answer 2

I'll start working on the rate...
 15.25- 8.5 =6.75       6.75/ 3= 2.25  <(This is the rate)
8.5- 2.25= 6.25         6.25- 2.25= 4 <(Now I work my way to the y-intercept)
The y-intercept is 4 and the rate, which I found along the way, is 2.25.

I hope my answer satisfies you.
