(08.06a) the line of best fit for a scatter plot is shown below:

what is the equation of this line of best fit?

1. y = -1/2x + 8

2. y = -2x + 8

3. y = -8x + 1/2

4. y = -8x + 2

you so much!

Step-by-step explanation:

lets pick 2 points on the line(6,5) and (10,3)

slope = (y2 - y1) / (x2 - x1)

(6,5)x1 = 6 and y1 = 5

(10,3)x2 = 10 and y2 = 3

now we sub

slope = (3 - 5) / (10 - 6) = -2/4 = -1/2

now we use y = mx + b

slope(m) = -1/2

u can use either of ur points...I will use (6,5)...x = 6 and y = 5

now we sub and find b, the y int

5 = -1/2(6) + b

5 = -3 + b

5 + 3 = b

8 = b

so ur equation is : y = -1/2x + 8 <===

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

hm let me think hm think think hm think yes
