A scatter plot was constructed and a line of best fit was drawn, 25x 80. What is the equation of this best line of fit?
Tcecarenko [31]

Answer:

y = 5x + 25

Explaination:

To get the equation of a line, first get the slope of the line.


Slope = (change in y)/(change in x)


          = (60-30)/(7-1)


          = 30/6


            = 5


Now use one point in the line (4,45) and a general point (x,y).


Slope = (change in y)/(change in x)


    5 = (y - 45)/(x - 4)


    5(x - 4) = (y - 45)


  5x - 20 = y - 45


y = 5x -20 + 45

The perimeter of a rectangle swimming pool is 160 feet. The length of the swimming pool is four times its width . Find the dimen
Helga [31]
Formula for Perimeter of Rectangle:

P = 2(L + W)

Plug in 160:

160 = 2(L + W)

L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)

160 = 2(4W + W)

Combine like terms:

160 = 2(5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4(16)

L = 64

So the width is 16, and the length is 64.</span>

Does this graph represent a function? Why or why not?
vlabodo [156]

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.
