Answer 2

we will have to derive the equations of both data

let's start with the table
pick 2 points
(4,100)(5,125)
determine the slope
Slope = y2-y1/x2-x1
Slope = 25

now use
y - y1 = m(x - x1)
to determine the equations where m is the slope
y - 100 = 25(x - 4)
y - 100 = 25x - 100
y = 25x

When x= 12 let's find the y value
y = 25(12)
y = 300

Now let's find the equation for the graph
pick 2 point again
(2,60)(4,120)
Slope = 30

y - y1 = m(x - x1)
y - 60 = 30(x - 2)
y - 60 = 30x -60
y = 30x
when x = 12
y = 30(12)
y = 360

The graph is 60 values more than the table

Answer 3

i'll have to go for a bit

Answer 4

wait i just have a few left.. please stay for just a couple more mins

Answer 5

rate of change is the slope
pick 2 point
(1,15)(2,30)
Slope = 15
