Given :
Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.
To Find :
How many hours must have passed if there are 5 inches of rain .
Solution :
Let , after x hours rain accumulated is 5 inches .
We know , general equation of line :
y = mx +c
Here , m = 0.5 and c = 1 .
So , equation of rain accumulated is :

Now , putting value of x = 5 hours .
We get :

Hence , this is the required solution .
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 gives the next term.

Answer:
Step-by-step explanation:
What does the graph look like
Answer:
y = 2x - 2
y = -x + 5
Step-by-step explanation:
First, look at the y-intercept of each line. On one line it is -2 and on the other it is 5. Then look at the amount the line goes up or down per x-notch. On one line it is 2 and on the other it is -1. Then sub in these values into the template y=mx+b and you will have your equations.
