(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 <===

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
