The form ym x-a is essentially different from the other two forms and means slope m and x-intercept instead of y-intercept a. In this form of the equation the m variable refers to the slope while the b variable refers to the y intercept. The form ymxb means slope m and y-intercept b.
Y mx b y mx b is for ease of graphing.
Next divide the equation by the constant 4 to isolate y giving you y 32x 52. You can use slope intercept form to solve for x y m and b. Before you learn an easy method for finding slope with and without a calculator lets make sure that you understand a few basics of slope including the slope definition. Assign which point is the first and second and then label its components.
