## magicalduckfish 2 years ago I really need help understanding this! 1. Which two points lie on a line with slope 2/3? (2, 0) and (3,0) (3, –4) and (1, 2) (0, 0) and (2, 3) (–3, 2) and (0, 4) 2. What is the slope of the line that passes through the given points? (6, –1) and (–3, –1) undefined 0 – 2/3 – 3/2 4. Write the equation in slope-intercept form. What are the slope and y-intercept? 3/4x + 4/5y = 4 y = 15/16x + 5; slope: 5; y-intcerpt: 15/16 y = 15/16x – 5; slope: 15/16 : y-intercept: –5 y = –15/16x – 5; slope: –15/16; y-intercept: –5 y = –15/16x + 5; slope: –15/16; y-intercept: 5

1. Which two points lie on a line with slope 2/3? use: m=(y2-y1)/(x2-x1) and plug in m which is slope and see which of the choices satisfies the equation 2/3=(y2-y1)/(x2-x1) It is (–3, 2) and (0, 4) (2-4)/(-3-0)=-2/-3=2/3 :)

It's still confusing o.O

3. aubreyk9614

do you go to connections academy

4. magicalduckfish

No but my schooling uses the same things as connections academy such as connexus and stuff like that :)

5. aubreyk9614

i recogizne the test that why i would help but i need unit name

6. magicalduckfish

Oh Functions, Equations, and Graphs : Linear functions and slope intercept.

7. timo86m

All you have to do for q 1 is use the slope formula which is. m=(y2-y1)/(x2-x1) where m is slope and it will be 2/3 y2 is 2nd y y1 is first y x2 is 2nd x x1 is 1st x and just start pluging in.

8. magicalduckfish

ohhhhhhhh okay. Got it.

9. timo86m

ook :D 2. What is the slope of the line that passes through the given points? (6, –1) and (–3, –1) you use the same formula y2 is 2nd y y1 is first y x2 is 2nd x x1 is 1st x |dw:1354601772235:dw|

4. Write the equation in slope-intercept form. What are the slope and y-intercept? 3/4x + 4/5y = 4 I think you skipped number 3. But the above is just solve for y and you effectively put it in y intercept form.

11. magicalduckfish

Thank you so much!!! :) Uhm I skipped 3 because I already got that one :P But thank you!

12. timo86m

13. magicalduckfish

Woaaaa wait I still kinda don't get 4 o.O

14. timo86m

simply solve for y 3/4x + 4/5y = 4 4/5y = 4-3/4x 4/5y = 5/4*(4-3/4x) y=5/4*(4-3/4x) y = -(15/16)*x+5 distriute 5/4 and rearrange

15. magicalduckfish

Oh okayyy! I tend to think things are more difficult than they really are. But thanks again :)

16. timo86m

Just take it slow and read carefully :D All things are very simple that way.

17. magicalduckfish

Yea, sure thing :)
