2. y X x - intercept y - intercept
Definitions. Instruct student to add to notebook.
y - intercept

3. Graphing using Intercepts
Let x=0 and determine the y-intercept.
Let y=0 and determine the x-intercept
Plot both points. Connect them with a line.

4. Graph y=x+4 using intercepts
Find x-intercept
0=x+4
Find y-intercept
Y=0+4
-4__-4
Y=4
-4= x
Teach and demonstrate the concept.

5. Graph 4x + 3y = 12 using intercepts
Find x-intercept
4x + 3(0) = 12
Find y-intercept
4(0) + 3y = 12
4x = 12
3y = 12
x = 3
y = 4
Teach and demonstrate the concept.

6. Graph y = -2x using intercepts
X- int
Y- int
Y=0
X=0
If your x and y intercept is (0,0) you need more ordered pairs to graph. Use a table to find the extra ordered pairs

7. Horizontal and Vertical Lines
The graph of y= # is HORIZONTAL
The graph x =# is VERTICAL

8. Graph y = 4 using 3-points x y 4 3 6

9. Graph x = 6 x y 6 3
- 4
