13. Using Intercepts

14. key terms
Y-intercept: ________________________________________ __________________________________________________ X-intercept: ________________________________________

15. Find the x- and y-intercepts for each graph below.
x-intercept:
y-intercept:
x-intercept:
y-intercept:

16. Finding intercepts when given an equation.
Step 1: Step 2: Step 3: Step 4:

17. 5x – 2y = 10
X-intercept
Y-intercept

18. 5x – 2y = 10

19. y = -x + 4
X-intercept
Y-intercept

20. y = -x + 4

21. y = ⅓x - 2
X-intercept
Y-intercept

22. y = ⅓x - 2

23. Try it: Find the x- and y-intercepts on the graph below.
x-intercept: y-intercept:

24. Try it: -3x + 5y = 30
X-intercept
Y-intercept

25. -3x + 5y = 30

26. Try it: -3x – 7y = 21
X-intercept
Y-intercept

27. -3x – 7y = 21

28. Try it: 4y = 3x - 12
X-intercept
Y-intercept

29. 4y = 3x - 12

30. Word Problem
Trish can run the 200 m dash in 25 seconds. The function f(x) = 200 – 8x gives the distance remaining to be run after x seconds. Graph this function and find the intercepts. What does each intercept represent? x 00 5 10 20 25
f(x)= 200-8x
200
160
120 40

31. Find the intercepts and graph the line
¼x = 2 - ⅓y
