Slide1Main Idea/Vocabulary• slope • rise • run • Find the slope of a line.

Slide2Example 1ACCESS RAMPS The access ramp from the sidewalk to the door of a hotel rises 8 inches for every horizontal change of 96 inches. What is the slope of the access ramp? Answer:

Slide31.A 2. B 3. C 4. D Example 1 ACCESS RAMPS The access ramp from the sidewalk to the door of an office building rises 14 inches for every horizontal change of 210 inches. What is the slope of the access ramp? A. B. C. D.

Slide4Example 2Find Slope Using a Graph Find the slope of the line. Choose two points on the line. The vertical change is –3 units while the horizontal change is 2 units.

Slide5Example 2Find Slope Using a Graph Answer: or

Slide11Example 4Find the slope of the line that passes through A (3, 3) and B (2, 0). Definition of slope Find Slope Using Coordinates ( x 1 , y 1 ) = (3, 3), ( x 2 , y 2 ) = (2,0) Simplify. Answer: The slope is 3.

Slide12Example 4Check When going from left to right, the graph of the line slants upward. This is correct for positive slope. Find Slope Using Coordinates

Slide131.A 2. B 3. C 4. D Example 4 A. –1 B. 1 C. 2 D. 5 Find the slope of the line that passes through A (4, 3) and B (1, 0).

Slide14Example 5Find the slope of the line that passes through X (–2, 3) and Y (3, 0). Definition of slope Find Slope Using Coordinates ( x 1 , y 1 ) = (–2, 3), ( x 2 , y 2 ) = (3,0) Simplify. Answer:

Slide15Example 5Check When going from left to right, the graph of the line slants downward. This is correct for a negative slope. Find Slope Using Coordinates

Slide161.A 2. B 3. C 4. D Example 5 Find the slope of the line that passes through X (–3, 3) and Y (1, 0). A. B. C. D.

Slide171.A 2. B 3. C 4. D Five Minute Check 1 Which of the following is a graph of the function y = x – 2? (over Lesson 9-3) A. B. C. D.

Slide181.A 2. B 3. C 4. D Five Minute Check 2 (over Lesson 9-3) Which of the following is a graph of the function y = 4 x ? A. B. C. D.
