Question

Can someone check my work and see if I did it wrong or right? If wrong please explain to me the right answer thanks! Medal+Fan (:

Answer 1

@tHe_FiZiCx99 @ml1042903

Answer 2

1st one is correct....2nd one i think u made a minor error in ur math; would u like to try again n see if u can figure it out? :)

Answer 3

the general eqn for 2 points is (y-y1)/(x-x1)=(y1-y1)/(x1-x2)
so (y-3)/(x--1)=(3-11)/(-1-1)
simplify n re-arrange...

Answer 4

A?

Answer 5

Nope....check out my eqn above plz :)

Answer 6

(y-3)/(x--1)=(3-11)/(-1-1)
(y-3)/(x+1)=-8/-2....

Answer 7

D? sorry I don't really get this stuff

Answer 8

Bingo - good job :)

Answer 9

The first one is correct, you made a small error on the second.

First find the slope, M = (y2-y1) / (X2-x1)

M = 11-3 / 1 - (-1)

M = 8 / 2

M = 4

So the slope is 4


Now write the equation, y-y1=m(x-x1)

y-3=4(x-(-1))

y-3=4x + 4
+3 +3

y = 4x + 7

So rewrite it

Answer 10

Thank you both! Oh god not sure who to give the medal too lol can you check two of my other questions?

Answer 11

sure

Answer 12

i will let some1 else help u now @mysticghost :)

Answer 13

Okay thanks for helping me before

Answer 14

@tHe_FiZiCx99 posted it ^ just help me when you can thanks (:

Answer 15

K um, parrallel have the same slope, perpendicular is the reciprocal, so flip it and multiply it by -1


You have the slope, so for parallel, just set up the equation.

y-y1=m(x-x1)

y-9=1/4(x-(-8))

y-9=1/4x + 2
+9 +9

y = 1/4x + 11 <-- this is the slope intercept form for parallel. Can you find the perpendicular one?

Answer 16

You already know the answer by just looking at it, but you're more than welcome to try, I'll correct you if your wrong :PP dw

Answer 17

Is it D?

Answer 18

How did you get D ?

Answer 19

well its the only one with a slop intercept for the parallel with y = 1/4x + 11
unless its A.

Answer 20

o.o lol but but.. i gave you the parallel you didn't try the perp one U_U

Answer 21

yes i know lol but if thats the parallel then D is the only answer with that one so thats why i think its D but i also think it could be A.

Answer 22

It's D U_U A is -11 >.<

Answer 23

I said it was D...

Answer 24

^ Idk, i guess i wanted to help you understand how to do both >.<

Answer 25

Oh well thank you!

Answer 26

yw :]

Answer 27

(: mind checking one more?

Answer 28

nope :p

Answer 29

It's all real numbers greater than 0 and less than 13

Answer 30

24 + 2x < 50
-24 -24

2x < 26
/2 /2

x < 13

Answer 31

Ohh I think I get it thanks!

Answer 32
