Chapter 8 – Functions and Graphing 8.6 – Slope-Intercept Form
When a linear equation is written in the form y = mx + b , it is in slope-intercept form. y = mx + b slope y -intercept
State the slope and the y -intercept of the graph of y = ½ x + 3. State the slope and the y -intercept of the graph of -4 x + 5 y = -10. You can use the slope-intercept form to graph a line quickly.
Graph y = ½ x – 5 using slope-intercept form. <ul><li>Graph the y -intercept. </li></ul><ul><li>Using “rise over run,” graph at least three other solution using the slope. </li></ul><ul><li>Connect the dots and extend your line. </li></ul>
Graph 3 x + y = 9 using the slope and y-intercept.
