Objective: Identify the slope and y-intercept of a line from its equation and graph an equation written in slope-intercept form.
A linear equation written in the form y = mx + b is said to be written in slope-intercept form. The graph of such an equation has slope m and y-intercept (0, b). Slope-intercept form provides a simple way to connect the graph of a line with its equation. Watch the video below.
It is possible to graph a linear equation written in slope-intercept form without generating a table of values. First, identify the slope and y-intercept of the line from the equation. Next, plot the y-intercept and use the slope to locate more points on the line. Finally, connect the points to graph the line. Watch the video below.
