## millitarygirl96 2 years ago 2 slope problems PLEASE help Write the equation of the line with a slope of -1/3 and passing through the point (6, -4). Write the equation of the line passing through the points (-6,1) and (-4,2).

1. zordoloom

For the first equation, use the point slope formula and plug in the given data

2. zordoloom

y+4=(-1/3)(x-6) ----->Now rearrange this if it is required. You can leave it like this since it is correct.

3. zordoloom

And for the second part, find the slope between the two points: (-6,1) and (-4,2).. And use one of the points to form the equation.

4. millitarygirl96

it has 2 b completely simplified and 4 the first 1 got y=-1/3x-6

5. zordoloom

huh?

6. zordoloom

It would have helped if you would spell out the words. And no, it is not y=-1/3x-6. Instead it is y=-1/3x-2

7. millitarygirl96

oh ok I see what I did wrong and sry im trying 2 type with 1 hand and it takes longer so im using short cuts

8. zordoloom

For the second part, can you find the slope between the two points?

9. zordoloom

The slope would be 1/2. Now pick either point and write the equation.

10. zordoloom

y-2=1/2(x+4)----> Now rearrange this and get y=1/2x+4

11. zordoloom

Hope this helped.

ok thanks :) do you understand this problem : Write the equation of the line with an undefined slope, passing through the point (2, 5).

13. millitarygirl96

I don't understand how u can write an undefined slope

14. zordoloom

undefined slope means the line is vertical. Therefore, the equation for the line would be y=2

15. zordoloom

wait, x=2.

16. millitarygirl96

so you don't do anything with the 5?

17. zordoloom

y=2 would be horizontal, so it would be x=2

18. zordoloom

5 is a point above the 2. Only the first variable matters, which is 2.

19. millitarygirl96

oh ok :) thank u sooo much
