X1 x2 are the coordinates of x-axis and y1 y2 are the coordinates of y-axis. The formula to calculate slope is given as mfrac y_ 2-y_ 1 x_ 2-x_ 1 Where m is the slope of the line. The formula to calculate slope is given as Slope of a Line m y2 - y1 x2 - x1 Where m is the slope of the line.
The basic formula for a linear equation is y mx b where m is the slope.
Look at the formula to find it example 1 Use a little algebra to get the equation in the right form example 2. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
