What is most likely the line of best fit for this scatter plot? graph shows numbers from 0 to 10 at increments of 1 on the x axis and numbers from 0 to 18 at increments of 2. scatter plot shows ordered pairs 1, 2 and 2, 3 and 3, 5 and 4, 6 and 5, 6 and 6, 7 and 7, 9 and 8, 9 and 9, 10 and 10, 12 and 11, 13 and 12, 14. a line labeled a joins ordered pair 0.8, 0 and 3.2, 22. a line labeled b joins ordered pairs 0.4, 0 and 8.5, 22. a line labeled c joins ordered pairs 0, 1 and 14, 14. a line labeled d joins ordered pairs 0, 1.5 and 14, 8 line a line b line c line d

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
