A vertical line has an undefined slope since it would result. You can also use this method if you are given two points on the line without having the line graphed in front of you. How can I calculate the slope between two data points.
Identify the coordinates x₁y₁andx₂y₂.
And the line passes through the 2 points given the equation of a line is y mx c where y is dependent on x m and c are constants and x is independent. My values look like this. Find the slope of the line that goes through the two points that are given to you. Finding the Slope of a Line from Two Points.
