1 Graph: x + y = 5 1. Solve for y. 2. Make an X|Y chart. 3. Graph

2 Graph: x – 3 = y 1. Solve for y. 2. Make an X|Y chart. 3. Graph

3 Graph: y= 2x Solve for y. 2. Make an X|Y chart. 3. Graph

4 Graph: 3x – 2y = 6 1. Solve for y. 2. Make an X|Y chart. 3. Graph

5 Graph: x = 4 1. Solve for y. 2. Make an X|Y chart. 3. Graph

6 Graph: y = Solve for y. 2. Make an X|Y chart. 3. Graph

7 You can check these on the graphing calculator. Press y = and type in the equation. Press Zoom Fit to look at equation. Press 2 nd Graph (Table) to see the x|y chart.

8 Finding intercepts. X- intercept: set y = 0 Y- intercept: set x = 0 X-intercept:y-intercept:

9 Find intercepts & graph.
