The formula becomes increasingly useful as the coordinates take on larger values or decimal values. Calculate the slope from 2 points. Y m x b.
That line goes down as you move along so it has a negative Gradient.
Starting from the left and going across to the right is positive. For this equation y 3x 2 is in slope intercept form. Slope y 2 y 1 x 2 x 1 text Slope. Make sure this slope makes sense by.
