Suppose oil spills from an offshore drilling platform and spreads in a circular pattern. if the radius of the oil spill increases at a constant rate of 5 feet per second, how fast is the area of the spill increasing when the radius is 40 feet?

is this the format that your looking for?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
