Alinear regression equation has b = 3 and a = – 6. what is the predicted value of y for x = 4?

The predicted value of y for x = 4 is 6

Step-by-step explanation:

Linear regression models are used to predict the relationship between two variables. The regression equation is usually expressed as:

where y is the dependent variable and x is the independent variable, a is the intercept on y axis while b is the slope of the regression line.

since a = -6

         b = 3

When x = 4,

∴ Predicted value of y = -6 + (3 x 4)

                                        = -6 + 12

                                            = 6

The predicted value of y for x = 4 is 6.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
