2. 3.01 Graphing lines

3. Ways to graph
If the equation is in slope intercept form (y=mx+b), use the y- intercept and slope
Plot the y-intercept then use the slope
If the equation is in standard form (Ax+By=C), use the x and y intercepts
Plug in zero for the x value to solve for the y intercept (C/A)
Plug in zero for the y value to solve for the x intercept (C/B)

4. Examples 2x-4y=8 C/B = 8/-4 = -2 2x-4y=8 C/A = 8/2 = 4 2(0) – 4y =8

5. Scatter plots

6. 3.02 Slope Rise over run: up (+) or down (-) and ALWAYS right ()
Slope formula:

7. 3.03 Writing Equations of Lines
Point-Slope Form:
Slope-Intercept Form:
If given two points, you can use the slope formula, then plug in the slope and one of the points to the point-slope form. If you need to get slope-intercept form, distribute the slope and move y1 to the right side.
