1. Do Now 1)What is the equation of the line passing through the points (0, 5) and (3, 6) ?

2. Graphing Lines In Slope – Intercept Form 1)Plot the y-intercept. 2)Write the slope as a fraction. * Put the negative on top if necessary 3)Use the slope to find more points starting at the y-intercept. 4)Draw the line and label the equation.

3. 2) Graph each line.

4. 3) Graph each line.

5. Which is the graph of y = x + 2? 1. 2. 3.4.

6. Equations Not In Slope-Intercept Form If the equation is not in slope-intercept form, you must solve it for y before you can graph it. Ex:3x + y = 4 - 3x - 3x y = – 3x + 4
