Using the equation ŷ = 2.6 − 3.1x, what is the predicted value if x is 4.3? Select one:
a. −10.73
b. 10.73
c. 15.93
d. −15.93
e. 0.54

Work Shown:

Plug x = 4.3 into the equation given

ŷ = 2.6 − 3.1x

ŷ = 2.6 − 3.1(4.3)

ŷ = 2.6 − 13.33

ŷ = -10.73

Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
