The scatter plot shows the amount of time Oscar played and the number of points he scored during each basketball game. Which describes the association of the variables in the data?

A ) no association

B) nonlinear association
Eliminate

C) positive, linear association

D) negative, linear association

C) positive, linear association

Step-by-step explanation:

Most of the plotted data can be reasonably approximated by tracing a straight line along the points that represents an increase in points scored as time played increases. Even though two of the instances plotted would not fit the linear model, those can be treated as outliers and, therefore, a positive, linear association between points scored and time played can be observed.

The answer is C) positive, linear association

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
