Answer:
Step-by-step explanation:
One
The y intercept is (0,35).
Two
The y intercept is the point that shows where the line cuts the y axis. It looks to me like it is about (0,35) as was stated above.
Two
You need to find the slope from one of the two points you are given. The other point is the y intercept.

(0,35)
(3,42.5)
Formula
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 42.5
y1 = 35
x2 = 3
x1 = 0
m = (42.5 - 35) / (3 - 0)
m = (7.5 / 3)
m = 2.5
