If you can I would like the answer as soon as possible thank you

Answer 1

1) Gathering the data

a)

(4,112) and ( 6,168)

Picking those points and inserting them in the slope-intercept formula:

Now plugging one point (4,112) into the y=mx +b, to find out b, the linear coefficient:

112=28(4) +b

112=112 +b

b= 0

So, the function for that is f(x) = 28x
