write an equation in slope- intercept form of the trend line

Answer 1

The slope-intercept form of a linear equation is written as:

y = mx + b

Where:
- y is the dependent variable,
- x is the independent variable,
- m is the slope of the line, and
- b is the y-intercept.

To write an equation in slope-intercept form for a given trend line, you need the values of the slope (m) and the y-intercept (b).

For example, if the slope of the trend line is 2 and the y-intercept is 3, the equation in slope-intercept form would be:

y = 2x + 3
