Now we can write a general formula for slope. The slope of a line characterizes the direction of a line. Y mx b or sometimes y mx c where.
Select one to be x 1y 1 and the other to bex 2y 2 Step3.
In slope-intercept form m is the slope and b is the y-intercept. The formula becomes increasingly useful as the coordinates take on larger values or decimal values. The formula for finding the slope of a line on a coordinate plane is y2 - y1 x2 - x1 where x2 y2 and x1 y1 represent two distinct points on the line. Y mx b or sometimes y mx c where.
