Lets look at another line. This line has a negative slope, it falls from left to right. We can take any two points on this line and find the slope.Equations Knowing how to find the slope and the y-intercept helps us to graph a line when we know its equation, and also helps us to find the equation of a line Now that we know how to calculate a slope, we must figure out how to graph the line. A line is often written in slope-intercept form, y mx b where m is the slope and b is the y-intercept.Either way, given two points, you can always find the slope of the line with that quick formula. -- You may be given three points that are on a circle, and asked to find the slope and intercept of a line that passes through the center of the circle.
