## MaeganR 2 years ago Standard Form? 10 Problems..

1. MaeganR

"Find the x- and y- intercepts of the graph of each equation." #1. x+y=7 #3. 2x+3y=-6 #5. 5x-4y=-12 "Draw a line with the given intercepts." #7. x-intercept: 4 y-intercept: 5 #9. x-intercept: -6 y-intercept: -8 "Graph each equation using x- and y- intercepts." #11. -3x-6y=12 "For each equation, tell whether its graph is a horizontal or vertical line." #13. y=-2 #15. y=-0.25 "Graph each equation." #17. y=6 #19. y=-7 EVEN IF YOU HELP ME WITH ONE OF EACH FROM EACH SET OF INSTRUCTIONS THAT WOULD BE GREAT. THANKS FOR ALL OF YOU WHO HELP ME! (:

for finding the x and y intercepts just cover the other variable .. for example x+y= 7 cover the x and you get y=7 cover the y and you get x= 7

3. MaeganR

so its 7?

4. erdog82

yup, I believe so

5. erdog82

try the same thing with the next two, when you think you have the answer, tell me it and I will tell u if its right

6. erdog82

ok?

7. MaeganR

crap. i just did #2 not #3 i only have to do odd. srry brb

8. erdog82

kk- r u using a textbook?

9. MaeganR

y=-2 x=-3

10. erdog82

yup ☺

11. MaeganR

we do have textbooks but my teacher doesn't let us use it. we only have what frayed diagrams she gives us and our workbook with just problems in it. ): the textbook would be reeeeally useful.

12. erdog82

oh..

13. MaeganR

yeah it sucks

14. erdog82

yup

15. MaeganR

#5. y=-3 x= -2.4 ?

16. erdog82

y= 3 but yah

17. MaeganR

oh yeah i see now #7 how do i do it. and btw i was out sick the whole week she taught all this so i never learned it so you're teaching me right now. (:

18. erdog82

Oh.. ok ☺ I feel your pain, I was sick and I had to teach myself

19. MaeganR

20. MaeganR

#7. ?

21. erdog82

no, you have to plot (0,5) and (4,0) on a graph and then just extend the line with a ruler

22. MaeganR

oh. i knew that.............

23. erdog82

yup ☺

24. MaeganR

gotta go get a ruler brb

25. erdog82

so do 7,9,and 11 because you now know how to do those ☺

26. erdog82

kk

27. MaeganR

ok ill be back in a few then

28. MaeganR

11. y=-2 x=-4

29. erdog82

yep!!

30. MaeganR

#13, 15 i need help now..

31. erdog82

ok the next 2 is hard to explain, but I remember it as "y ski" aka why ski.. if it is only y then it is horizontal, so why would you ski on no slope..

32. MaeganR

so #13. y=-2 is horizontal? and #15. y=-0.25 is horizontal also?

33. erdog82

yup!!

34. erdog82

so for 17 and 19 you put a dot on the point it says and then extend the horizontal line with a ruler..

35. MaeganR

wait, so if it was like x=0 or x= -3/5 it would be vertical? with a slope?

36. erdog82

it would be vertical i think for the first one, i'm not sure about the second 1

37. MaeganR

oh so anything with y is horizontal but x you have to find out?

38. erdog82

i'm not 100% sure about x.. I am only just learning this stuff too

39. erdog82

sorry

40. MaeganR

oh lol

41. erdog82
