## anonymous one year ago I NEED SOME EMERGENCY HELP WILL MEDAL AND FAN PLEASE!!!! Indicate in standard form the equation of the line passing through the given point and having the given slope. D(5, -2) m = #2ndicate in standard form the equation of the line passing through the given points. B(0, 0), C(4, -4) #3ndicate in standard form the equation of the line passing through the given points. P(6, 2), Q(8, -4) #4Indicate in standard form the equation of the line passing through the given points. G(4, 6), H(1, 5)

What is the value of m for the first part? You appear to have missed typing it.

2. anonymous

2/5

3. anonymous

sorry

4. kropot72

You need to substitute the given values into the equation y = mx + b and rearrange into standard form.

5. kropot72

This will let you find the value of b which is the y-intercept.

6. anonymous

okay so 5x-2y=2/3?

7. anonymous

wait i think im off

8. anonymous

what am i doing wrong?

9. kropot72

Substitute the given values into y = mx + b. Then solve to find the value of b. Can you do that as a first step?

10. anonymous

no i dont think so

11. anonymous

this is what it looks like _x__y__

12. kropot72

y = -2, x = 5 and m = 2/5 Plug these values into y = mx + b What do you get?

13. anonymous

do i x 2/5 and 5?

14. kropot72

Correct.

15. anonymous

that would be 2

16. kropot72

So we should have -2 = 2 + b which needs to be solved to find the value of b.

17. anonymous

yes

18. anonymous

ugh i dont know do we x 5 and 2?

19. kropot72

What do you get for the value of b?

20. anonymous

10? *I say very unsure*

21. kropot72

Can you solve -2 = 2 + b to find the value of b?

22. anonymous

oh wait i felt like it was harder then it was i hope would b be -4?

23. anonymous

so it would be -2=2+-4?

24. kropot72

Yes, b = -4. So we now have $\large y=\frac{2}{5}x-4$ which needs to be rearranged into standard form ax + by = c

25. anonymous

how would i do that?

26. anonymous

oh wait

27. anonymous

whats a?

28. kropot72

First interchange the left and right sides to give $\large \frac{2}{5}x-4=y$ Then rearrange to give $\large \frac{2}{5}x-y=4$ Now you need to remove the fraction by multiplying both sides by 5.

29. anonymous

oh okay

30. anonymous

hahaha hold i thats so wrong

31. anonymous

i hate math

32. anonymous

10x-y=4?

33. kropot72

$\large 5(\frac{2}{5}x-y)=4\times5$ which becomes $\large 2x-5y=20$

34. anonymous

oh lol i feel stupid now

35. anonymous

thank you soooo much i think now i can figure out the rest now

36. kropot72

You're welcome :)
