Hank counted the number of scratches on cars of different ages. Hank then created the scatter plot below showing the relationship between the age of a car (x) and the number of scratches found on the car ly). Part A
In 3-4 sentences describe why this is the line of best fit for the data shown on the graph. Be sure your explanation includes the following words
- Positive correlation or Negative correlation
-line of best fit
-Strong Correlation or Weak Correlation
-data points
scatter plot
Part B
Use the line of best fit to predict the number of scratches in a car when the age of the car is 30 years old. Explain how you arrived at your conclusion

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
