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 .
Solution:
we have been asked to find
Which equation represents the graphed function?
As we can see in the graph, the line is passing through the point (2,0) and (0,-3).
As we know the equation of the passing through two points is given by the formula
So the equation of the line will be
