X-Intercepts & Y-Intercepts Graphing

Bellwork l l Complete task Unit 4 Lesson 2 Task #2 on Page 5 in your workbook. This will be graded for as a classwork grade at the end of the unit.

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

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

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

Find the x-y-intercepts and graph 1. 4 x + y = 5 To find the x-intercept, make y = 0 Solve for x (divide by 4) The x intercept is

Find the x-y-intercepts and graph 1. 4 x + y = 5 To find the y-intercept, make x = 0 Solve for y The y intercept is

Graph: 4 x + y = 5 l l x-intercept is (1. 25, 0) y-intercept is (0, 5)

Classwork l l 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

Find the x-y-intercepts and graph 2. x – y = 1 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)

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

Find the x-y-intercepts and graph 3. x + 4 y = 8 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)

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