The line of best fit for a data set is y = 1.12 + 3.4 What is the residual for the following coordinate pair: (2.5, -5.95)

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

depends on how many days you are talking about

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
