Answer:
Step-by-step explanation:
First, we need to find the y-intercept. The y-intercept is the intersection of the point on the y-axis. We can clearly tell that the y-intercept is 1. The slope is definitely 0 because it shows a straight line.
Hence, the equation is y = 1.

Answer:
The time it took until 2 inches of rain fell is 8 hours
Step-by-step explanation:
You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x
To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:
2= 0.25*x
Solving:
8 = x
So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.
