y=1/2x+3.5
Step-by-step explanation:
this one was a bit trickier than the previous one, but i think that that answer is correct. i did the same thing i did to solve your last problem, solved for the slope, and then made a number line and marked the points given, drew a line through the two points, and found where the line intercepted the y axis.
Answer: 
Step-by-step explanation:
The circular oil slick is expanding at a rate of 
Let A be the area of the circular oil slick,
So, the changes in A with respect to time (t),
Also, the change in diameter with respect to time(t),
For r = 1.5 m,
![\frac{d}{dt} ( 2 r)]_{r=1.5} = \frac{2}{\pi \times 1.5}=\frac{20}{\pi \times 15}=\frac{4\pi }{3}\text{ meter per hour}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdt%7D%20%28%202%20r%29%5D_%7Br%3D1.5%7D%20%3D%20%5Cfrac%7B2%7D%7B%5Cpi%20%5Ctimes%201.5%7D%3D%5Cfrac%7B20%7D%7B%5Cpi%20%5Ctimes%2015%7D%3D%5Cfrac%7B4%5Cpi%20%7D%7B3%7D%5Ctext%7B%20meter%20per%20hour%7D)
