Question

need help on questions 4-7 HARD GEOMETRY WORK :/

Answer 1

for 4. and 5. find the slopes
if they are equal then parallel
if negative reciprocal of each other then perpendicular.

Answer 2

so is 4 parallel?

Answer 3

correct.

Answer 4

and 5 is perpindular right?

Answer 5

slopes of 5th are

Answer 6

did you get my message? and what do I do with question 6

Answer 7

\[\frac{ 4-6 }{ -2-5 }=\frac{ -2 }{ -7 }=\frac{ 2 }{ 7 }\]
and\[\frac{ 6-7 }{ 4-3 }=\frac{ -1 }{ 1 }=-1\]

Answer 8

now what can you say?

Answer 9

neither slopes are equal or negative reciprocal of each other.

Answer 10

what is that for of what you just put up? which question?

Answer 11

5th ,slopes

Answer 12

so for number 5 its neither?

Answer 13

\[slope ~of~a~line~passing~through~ two~points=\frac{ y _{2}-y _{1} }{ x _{2}-x_{1} }\]

Answer 14

correct.

Answer 15

what do I do for number 6?

Answer 16

for two lines parallel slopes are equal.
so you can delete two options for 6th.

Answer 17

so it can be either b or d

Answer 18

you have to delete B and D
check for A and C
for the remaining option substitute the given point and check for which it is true.

Answer 19

its a

Answer 20

??

Answer 21

no

Answer 22

@sshayer you there?

Answer 23

I double checked and everything :( omg im going to fail

Answer 24

Wait its the other one I just tried again

Answer 25

put x=-4 ,y=-1 in C

Answer 26

for 7th
\[midlle~ point x=\frac{ x _{1}+x _{2} }{ 2 },y=\frac{ y _{1}+y _{2} }{ 2 }\]

Answer 27

i got 7 already

Answer 28

so for 6 is it c

Answer 29

@lisa2345
For #6
All equations of parallel lines have the same slope.
Can you tell me the slope of the line:
y=(1/2)x+6
