## desperado 2 years ago Choose the slope-intercept equation of the line that passes through the point (–2, 2) and is parallel to y = 4x + 7.

• This Question is Closed
1. andriod09

first thing is first, do you understand the slop intersecept concept?

2. desperado

y = 4x + 10 y = 1/4 x + 5/2 y = -4x - 6 y = – 1/4 x + 3/2

3. desperado

somewhat

4. andriod09

$\frac{ \Delta y }{ \Delta x }$

5. andriod09

that is the change of y, over the change of x

6. andriod09

so type the equation using $\frac {\Delta y} {\Delta x}$

7. desperado

example please? /:

8. andriod09

lets take you last answer and try it. okay?

9. desperado

okay

10. andriod09

$\frac {\Delta y} {\Delta x}$ $y=\frac {-1} {4}x + \frac {3} {2}$

11. desperado

2/6

12. andriod09

but first you have to find the y

13. andriod09

so find the why first.

14. desperado

wouldn't it be 2? -1+3

15. andriod09

yup! that 's correct, now fill in $\frac {\Delta y} {\Delta x}$

16. desperado

I still stick with my guess of 2/6

17. desperado

I know that my answer isn't correct, but I'm not sure what I'm doing wrong

18. andriod09

no, you have to fill out the equation. use the equation button to fill it out

19. desperado

rephrase please?

20. desperado

im sorry i just dont get it

21. andriod09

okay, put the answer you got for y, in the $\Delta y$ and then what you got for x in the $\Delta x$

22. desperado

can you show me?

23. andriod09

yeah. give me your x and your y first and i'll show you.

24. desperado

2/6

25. andriod09

is that your x or your y?

26. desperado

i would say that 2 is my x and 6 is my y but im assuming that isn't correct

27. andriod09

how about we start on the actual problem, it would be alot less confusing.

28. desperado

ok

29. andriod09

so show me the $\frac {\Delta y} {\Delta x}$ with the shown intergers

30. desperado

I'm sorry but I really don't understand any of this. Can you tell me the answer and explain why it's so?

31. andriod09

wow i just realized something, you just have to graph the equation and then plot the points. -.-

32. desperado

yeahh lol i think we do too

33. andriod09

so graph them and tell me what you get. BTW: try answers b and c. :D

34. desperado

C?

35. andriod09

:D correct.

36. desperado

Thanks! Can you please help with one more?
