In slope-intercept form m is the slope and b is the y-intercept. Linear functions are very much like linear equations the only difference is you are using function notation fx instead of y. The way to solve a linear equation is to rewrite it in such a form that on the one side of the equality sign we end up with one term only containing x and on the other side we have one term which is a constant.
Substitute either point into the equation.
The slope of the line is whatever number is multiplied on the x variable so just solve the equation for x to figure out the slope. Slope-Intercept Form of the Equation of a Line. M is the slope and b is the y-intercept. By using this website you agree to our Cookie Policy.
