12.1 Linear Equations

Linear regression for two variables is based on a linear equation with one independent variable. The equation has the form:

y = a + b * x where a and b are constant numbers.

The variable x is the independent variable, and y is the dependent variable. Typically, you choose a value to substitute for the independent variable and then solve for the dependent variable.

Examples of linear equations:

y = 3 + 2x

y = –0.01 + 1.2x

Yes

Answer 2

Answer:

The slope intercept form of the line is

y=

mx+

c

, where

mis the slope of the line and cis they-intercept.

Change the equation

4x−

2y=

−1

in slope intercept form:

4x− 2y= −1

−2y= −4x− 1

y= 2x+

Therefore, the slope of the line

4x−

2y=

−1

is

m=

.

Since the parallel lines have same slope.

Hence, the slope of the line parallel to the line

4x−

2y=

−1

is

m=
