## jackyluvv 2 years ago really need help. dont understand Given the points (2, 3) and (6, 8), write the point-slope form of the equation. A. y - 3 = x - 2 B. y - 3 = 5/4 (x - 2) C. y - 8 = 4/5 (x - 6)

1. Brittni0605

Do you know what point slope form is?

2. zordoloom

Start by finding the slope between the two points: (2, 3) and (6, 8)

3. zordoloom

Once you have the slope between the two points, use of the points and the point slope formula to create the proper equatioo.

4. zordoloom

*equation

5. jackyluvv

how do i find the slope?

6. zordoloom

Subbtract the y-values and then subtract the x values. Then divide the resultant y values over the x values.

7. zordoloom

(2, 3) and (6, 8), the y values are 8 and 3. the x values are 6 and 2. So 8-3=5 and 6-2=4. Now divide 5/4... This is your slope.

8. jackyluvv

the slope is 5/4 or do i divide that first then i will have the slope?

9. zordoloom

5/4 is the slope

10. jackyluvv

ok now what do i do next?

11. zordoloom

now use the formula y-y1=m(x-x1). Replace m with the slope that you just found. and x1,y1 with one of teh coordinate points that were give.

The annual interest rate of Jacques' savings account is 3.6%, and simple interest is calculated monthly. What is the periodic interest rate of Jacques' account?

13. jackyluvv

where would i put the coordinate that i choose?

14. zordoloom

y-y1=m(x-x1). So replace m with 5/4.. This will look like y-y1=5/4(x-x1). Now say you chose to use the point (2, 3). This will look like y-3=5/4(x-2) If you were to use the point (6, 8), you will get something like y-8=5/4(x-6) both y-8=5/4(x-6) and y-3=5/4(x-2) are the same answers. It just will take some math to work them around to notice that.

15. jackyluvv

so it could be either one of those answers?

16. zordoloom

Yes

17. jackyluvv

thank you so much for your time and all of your help. i truly appreciate it

18. zordoloom

But look what choices you have in the multiple choice. The only one that matches that is B: y-3=5/4(x-2)

19. jackyluvv

ok thank you

20. zordoloom

Yep
