Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
<em>Table 1</em>
step 1
Find the slope
take two points from the data in the table
(0,3) and (3,15)
The formula to calculate the slope between two points is equal to
substitute
step 2
Find the linear function in slope intercept form
we have
substitute
<em>Table 2</em>
step 1
Find the slope
take two points from the data in the table
(2,5) and (5,11)
The formula to calculate the slope between two points is equal to
substitute
step 2
Find the linear function in slope intercept form
we have
Solve for b
substitute
therefore
