The coefficients of the linear relation are:
- Initial value = 5
- Rate of change = 1.25
<h3>How to find a linear equation?</h3>
A general linear equation is given by:
y = a*x + b
Where a is the slope (also called the rate of change) and b is the y-intercept (also called the initial value).
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is given by:
Here we will use only need the first two pairs from the table (you can use any two you want).
(0, 5)
(5, 11.25)
From the first one, you can see that when x = 0, y = 5.
Replacing that in the general linear equation we get:
5 = a*0 + b
5 = b
So we already know the initial value. Now we can use these two points to get the slope (rate of change).
Then we can conclude:
- Initial value = 5
- Rate of change = 1.25
