Question

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

Answer 1

The equation of a trend line in slope-intercept form is:

y = mx + b

Where:
- y is the value of the dependent variable (vertical axis)
- x is the value of the independent variable (horizontal axis)
- m is the slope of the line
- b is the y-intercept

To find the equation of the trend line in slope-intercept form, you need to calculate the slope (m) and the y-intercept (b) using the data points from the scatter plot. Once you have those values, you can plug them into the equation above to get the equation of the trend line.
