Graphing lines
- 1. Graphing Two Lines Are the lines parallel? Do lines intersect at a point?
- 2. Graph Two Lines Graph the two lines. Are they parallel? Why or why not.
- 3. Do we need to do anything to y = -3x? Step 1: Rewrite both equations in slope-intercept form. Reminder, slope-intercept form: y = mx + b. Do you notice anything about the slopes of the two equations? No, y = -3x is already in slope-intercept form. The two lines have the same slope, -3.
- 6. Are these lines parallel?
