The equation is y= 1.5x+38.5 and the value of y-intercept is 38.5
What is slope and y-intercept?
- The values of the slope and y-intercept reveal details of the relationship between the two variables, x and y.
- The slope shows how quickly y changes for every unit change in x. When the x-value is 0, the y-intercept shows the y-value.
Standard form of a slope intercept form is
y= mx+c
here m is slope. This is rate of y increases as x increases by 1,
C is y intercept, this is the value of y at start(when x=0).
Here y is amount collected. Here we have 38.5 at start. So C= 38.5
In each week amount (y) increases by 1.5. So m=1.5
Substitute in the standard form: Then,
y= 1.5x+38.5
Hence, the equation is y= 1.5x+38.5 and the value of y-intercept is 38.5

Let say the length of the rectangle is x. The material that can be used would determine the perimeter of the rectangle. Using the perimeter formula you can find the rectangle width
perimeter= 2(width+length)
400= 2(width + x)
200= width+x
width= 200-x
The function to determine the area would be:
area= length * width
area= x* (200-x)
area= 200x- x^2
To find the highest area you need to find out the vertex by finding the value of x when the differentiate of the function equal to zero.
dx/dy= 200- 2x = 0
2x= 200
x=100
If you put x=100 into the area function you will find
area= 200x- x^2
area= 200(100)- (100)^2
area= 20,000 - 10,000= 10000 feet^2
