Linear Equations and Graphs

Graphing a Linear Function Using the y-intercept and Slope

 

Let y = mx + b where m = (change in y-coordinates)/(change in x-coordinates) =Δy/Δx.

Click on the Show button to see the step-by-step process of drawing a linear function using a y -intercept and slope.

First plot the y-intercept.
From the y-intercept, move a horizontal distance of delta x.
From this point, move a vertical distanceof delta y. Call this point P.
Draw a line through the y-intercept and P. This is the line y =mx+b.
