What is the linear function equation that best fits the data set? 15 14 13 + 12 + 11 + 10 9 ŷ = -x +9 o ŷ = 3x + 15 ŷ = -3x + 15 ŷ= - 4/3x + 10 8 7+ 6. 5+ 4+ 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15​

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

what shape is

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
