Answer:
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
Find the slope
The formula to calculate the slope between two points is equal to
take the points
(0,2.5) and (100,97.5)
substitute in the formula
Find the y-intercept b
we have
substitute i the linear equation
solve for b
Note It was not necessary to calculate the value of b because the value is given in the table
Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))
The linear equation is
