In the linear equation y = mx + b, y-intercept represents the value of y. It is the point where the line crosses the y-axis(vertical axis)
Finding the y-intercept is done by looking at which point in the graph crosses the y-axis. This point will always have an x-coordinate of zero(0).
Step-by-step explanation:

Replace x and y.

Solve for y.

Square both sides.


This is the inverse function or you can also say

It should be 3,000

There are 52 weeks in a year, so subtract 27 from 52.
52-27=25
There were 25 weeks with no rainy days
