D.
you cannot have a negative amount of rainfall, so the predicted value of -32.4cm doesn't make sense.
Given:
The equation of line is

To find:
The x and y-intercept of the given line.
Solution:
We have,

Putting x=0, we get

Add 6 on both sides.


Divide both sides by 4.

So, the y-intercept is
.
Putting y=0 in given equation, we get

Add 5 on both sides.


Divide both sides by 7.

So, the x-intercept is
.
Your answer will be 2 2/4. If you want it simplified it will be 2 1/2
