Gold Day – 2/5/2015 Blue Day – 2/10/2015

2
Label “Slope Dudes” ski path way.

3
Friday, 2/13/2015 is the last day of the 4 th 6 weeks. Monday, 2/16/2015 is a student holiday Test corrections – Need to be done this week Unit 5 – Linear functions and Applications Start slope-intercept form Human slope

5
Linear functions – is a function that graphs a line. Parent function – is the simplest equation of a function. The linear parent function is y=x or f(x)=x Linear equations model linear functions. In a linear equation, the variable cannot be raised to a power other than 1.

6
Slope-Intercept form is y=mx+b

7
Locate the x and y axis Number all 4 ways starting from the origin. (0,0) Need Packet and Pencil

8
Assigned x-coordinate________ If y=x, then your y-coordinate is equal to the x-coordinate. X-coordinate is _____ which is also _____. Ordered pair is (____,____)

9
What is your equation? Graph what you see.

10
Assigned x-coordinate________ If y=-x, then your y-coordinate is equal to the negative x-coordinate. X-coordinate is _____, so y is -_____. Ordered pair is (____,____)

11
What is your equation? Graph what you see.

12
Assigned x-coordinate________ If y=x+3, then your y-coordinate is equal to the x-coordinate plus 3. X-coordinate is _____, so y is _____+3. Ordered pair is (____,____)

13
What is your equation? Graph what you see.

14
Assigned x-coordinate________ If y=x – 3, then your y-coordinate is equal to the x-coordinate minus 3. X-coordinate is _____, so y is x – _____. Ordered pair is (____,____)

15
What is your equation? Graph what you see.

16
Assigned x-coordinate________ If y=3x, then your y-coordinate is equal to the 3 multiplied by the x-coordinate. X-coordinate is _____, so y is 3 _____. Ordered pair is (____,____)

17
What is your equation? Graph what you see.

18
Assigned x-coordinate________ If y= ⅓ x, then your y-coordinate is equal to the ⅓ multiplied by the x-coordinate. X-coordinate is _____, so y is ⅓ _____. Ordered pair is (____,____)

19
What is your equation? Graph what you see.

20
Let’s look back at the graphs and compare. What do you notice? What do you think the reason for the difference? y=x and y=-x ____________________________________

21
Let’s look back at the graphs and compare. What do you notice? What do you think the reason for the difference? y=x+3 and y=x–3 ____________________________________

22
Let’s look back at the graphs and compare. What do you notice? What do you think the reason for the difference? y=3x and y= ⅓ x ____________________________________
