Answer 1

Line AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4). Lines AB and CD are

A) parallel because the slopes are the same

B) perpendicular because the slopes are the same

C) parallel because the product of the slopes is −1

D) perpendicular because the product of the slopes is −1

Answer 2

what was your answer?

Answer 3

B

Answer 4

no cannot be b or c
perpendicular lines the product of the slope =-1
parallel lines the slopes =

Answer 5

find the slope of each line

Answer 6

6/3


10/3

Answer 7

check your work and reduce to the lowest term

Answer 8

slope 2

Answer 9

can you show me how the slope is two?

Answer 10

6/3 = 2

Answer 11

ohhh ok

Answer 12

6-4/1-0 =2/1 =2

Answer 13

since the slopes are the same then they are parallel lines
answer a

Answer 14

ohh ok I understand now you think you can check a few more answers for me to see if im right?

Answer 15

Line CD contains points A (4, −7) and B (4, 8). The slope of line CD is

A) zero

B) undefined <---- My answer

C) positive

D) negative

Answer 16

8--7/4-4 agree

Answer 17

Yay ! So its B???

Answer 18

The equation of line AB is (y−3) = 5 (x − 4). What is the slope of a line perpendicular to line AB?

A) −5

B) 5

C) -1/5 <---- my answer

D) 1/5

Answer 19

great!

Answer 20

The equation of line WX is y = −2x − 5. Write an equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2).

A) y = 1/2x + 3/2

B) y = - 1/2x + 3/2

C) y = 1/2x − 3/2

D) y = − 1/2x − 3/2 <------ my answer

Answer 21

-2 m =-1
m = -1/-2 = 1/2
point (-2, -1)
-2 = 1/2 (-1) + b
b = -2 + 1/2 = -3/2
y = 1/2 (x) -3/2

Answer 22

ans c

Answer 23

so its C?

Answer 24

Ok last one

Answer 25

The equation of line CD is y = −2x − 2. Write an equation of a line parallel to line CD in slope-intercept form that contains point (4, 5).

A) y = −2x + 13 <---- My answer

B) y = negative 1/2x + 7

C) y = negative 1/2x + 3

D) y = − 2x − 3

Answer 26

show your work

Answer 27

ok give me a min

Answer 28

yes its correct!!
