Divide by B to simplifyIn the equation By -Ax C B needs to be distributed through the equation. It was changed to y -1x 12 so it will look like y mx b slope intercept form. And for a line this will always be constant.
Select the Label drop-down and select Use Equation.
And sometimes you might see it written like this. 12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be. The method for finding the slope from an equation will vary depending on the form of the equation in front of you. For these types of trend lines youll be able to find an equation in the slope-intercept form where m is your slope and b is your y -intercept.
