This will be graded for as a classwork grade at the end of the unit.

3. Objective Find x- and y-intercepts
Use x and y intercepts to graph a line

4. What are the x- and y-intercepts?
The x-intercept is where the graph crosses the x-axis.
The y-coordinate is always 0.
The y-intercept is where the graph crosses the y-axis.
The x-coordinate is always 0.
(2, 0)
(0, 6)

5. How to find To find the x-intercept, set y = 0
To find the y-intercept, set x = 0

6. Find the x-y-intercepts and graph
To find the x-intercept, make y = 0
Solve for x (divide by 4)
The x intercept is

7. Find the x-y-intercepts and graph
To find the y-intercept, make x = 0
Solve for y
The y intercept is

8. Graph: 4x + y = 5
x-intercept is (1.25, 0)
y-intercept is (0, 5)

9. Classwork In groups of 2, complete Unit 4 Lesson 2 Task #4 on page 8
This will be graded as classwork activity at the end of this unit

10. Find the x-y-intercepts and graph
To find the x-intercept, make y = 0
Solve for x (divide by 4)
x-int: (1, 0)
To find the y-intercept,
Make x = 0
y-int: (0, -1)

11. Graph: x – y = 1
x-intercept is (1, 0)
y-intercept is (0, -1)

12. Find the x-y-intercepts and graph
To find the x-intercept, make y = 0
Solve for x (divide by 4)
x-int: (8, 0)
To find the y-intercept,
Make x = 0
y-int: (0, 2)

13. Graph: x + 4y = 8
x-intercept is (8,0)
y-intercept is (0, 2)
