the slope of the linear equation is 2.25, which means that the third option is the correct one.
Remember that a linear equation is a function of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the linear equation passes through the points (x₁, y₁) and (x₂, y₂), then the slope of the line is:
a = (y₂ - y₁)/(x₂ - x₁)
From the given data, where we have:
We can use the first two points:
(2, 8.50)
(5, 15.25)
Replacing that in the slope equation we get:
a = (15.25 - 8.50)/(5 - 2) = 2.25
Then the slope of the linear equation is 2.25, which means that the third option is the correct one.
