2.1.3 Graphing Linear Functions (continued) Example 4 Graphing Functions in Slope-Intercept Form
Linear functions can be expressed as linear equations of the form y = mx + b . When a linear function is written in the form y = mx + b , the function is said to be in slope-intercept form because m is the slope of the graph and b is the y -intercept. A linear equation can be written in slope-intercept form by solving for y .
