First let's get rid of the in the denominator of the fraction on the right side of the equation. This will help to get only
and a coefficient on one side of the equation:
Now, simply divide by 730 to find :
Answer:
Step-by-step explanation:
From the graph,
The initial red incline is a straight line passing through the origin.
So, a straight line passing through the origin is of the form:
Where, 'm' is the slope.
Now, the slope of a given as the change in y value to change in x value.
Consider the two end points of the red line (0, 0) and (4, 6).
The slope with two points on the line is given as:
Plug in . Therefore, slope is:
Hence, the equation of the initial red incline is:
