## Kagome_gurl8 3 years ago Write in standard form, an equation of the line passing through the given point with the given slope. slope = –8; (–2, –2)

1. Kagome_gurl8

8x + y = –18 –8x + y = –18 8x – y = –18 8x + y = 18

2. Australopithecus

use y=mx + b where, m = slope b = y-intercept (the y-intercept is the point where x = 0)

3. Australopithecus

Just sub the slope that is given, and the x and y value of the point and solve for b. Remember a point in this case is defined as (x,y)

4. Australopithecus

once you have solved for b just sub along with the slope into the equation y = mx + b remember the y value is the output and the x value is the input, so they are changing the slope and y-intercept are constants

5. Australopithecus

any questions?

6. Kagome_gurl8

So it would be B?

7. Australopithecus

lol yes, wow they might as well have given you the answer

8. Kagome_gurl8

Yay!

9. Australopithecus

I hope you still go through the problem even though the answer is so evident to understand why it is correct

10. Kagome_gurl8

I do and will. :)

11. Australopithecus

-8(-2) + b = (-2) b = -16 - 2 b = -18 y = (-8)x + (-18)

12. Australopithecus

y + 8x = -18

13. Australopithecus

so no it is not b sorry I read the answers wrong ha I'm half asleep

14. Kagome_gurl8

It happens to the best of us. :)

15. Australopithecus

but yeah I hope you follow what I'm saying this stuff is important

16. Australopithecus

even though it may not at the moment seem interesting or relevant
