## anonymous 5 years ago Line s passes through the points (2, 7) and (6, 1). Line t passes through the point (5, 2) and is perpendicular to line s. What is the equation for line t?

1. anonymous

What is the equation for the slope of a line if you have 2 points on the line?

2. anonymous

idk

3. anonymous

are you asking from my question

4. anonymous

y2-y1over x2-x1

5. anonymous

$Slope = \frac{\Delta y}{\Delta x} = \frac{y_2-y_1}{x_2 - x_1}$ Right.

6. anonymous

i think im not sure

7. anonymous

So use the two points on the line s to find the slope of s.

8. anonymous

can you do it for me please im not fealling good i cant think right

9. anonymous

If you are not feeling well, you should be resting, not doing math.

10. anonymous

well i have to do this or i will get a 0 in my class

11. anonymous

i have no choice

12. anonymous

Ok then, go for it.

13. anonymous

what do you mean?

14. anonymous

i will try just for you lol

16. anonymous

wait how do you do it when you use the equation?

17. anonymous

which points do u use in the equation?

18. anonymous

You pick two points that are on the line you are solving the slope for. Those points are $$(x_1,y_1)\text{ and } (x_2,y_2)$$

19. anonymous

so (2,7) and (6,1) ?

20. anonymous

Yep

21. anonymous

oh ok thx so much

22. anonymous

i got -6/4

23. anonymous

is that right?

24. anonymous

Yep. That is the slope of the line s.

25. anonymous

i need to know an equation

26. anonymous

how do i use a slope for the equation?

27. anonymous

how do i use slope to find the equation?

28. anonymous

hello?

29. anonymous

you suck
