In this section, we outline a process to easily determine two points using the \(y\)-intercept and the slope. The equation of any nonvertical line can be written in slope-intercept form \(y=mx+b\). In this form, we can identify the slope, \(m\), and the \(y\)-intercept, \((0, b)\).
For each problem, find the x-intercept and the y-intercept and plot those points on the graph (use and re-use box 2). Then visualize/sketch the graph. Finally, graph the equation (use and re-use box 3) and compare.
An interactive simulation to explore and practice graphing lines in slope-intercept form, connecting the slope and y-intercept to the equation.
Learn how to graph a line using Slope and y-intercept. Know the equation of the line, identify the values of slope and y-intercept, and easily plot the line!
The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation. The equation can be in any form as long as its linear and and you can find the slope and y-intercept.
Demonstrates, step-by-step and with illustrations, how to use slope and the y-intercept to graph straight lines.
