Question

Please help

The slope of x = 1 is undefined.


A.True


B.False

Answer 1

hint: x = 1 is a vertical line through x = 1 on the x axis

Answer 2

so its false @jim_thompson5910

Answer 3

are you sure?

Answer 4

yes @jim_thompson5910

Answer 5

well horizontal lines have a slope of 0

vertical lines have an undefined slope

Answer 6

o ok so it false

Answer 7

@jim_thompson5910

Answer 8

which one is it? true or false?

Answer 9

its false @jim_thompson5910

Answer 10

horizontal lines have a slope of 0

vertical lines have an undefined slope


what type of line is x = 1 again? vertical or horizontal?

Answer 11

horizontal @jim_thompson5910

Answer 12

no that would be things like y = 1 or y = 10, etc

Answer 13

ok then its verical

Answer 14

yes so because it's vertical, it has an undefined slope

Answer 15

that mean it true? @jim_thompson5910

Answer 16

yes the answer is true

Answer 17

thank you can u help me with one more @jim_thompson5910

Write the slope-intercept form of the equation for the line


A.y = 3x - 1


B.y = 1/3 x + 1


C.y = -3x - 1


D.y = 1/3 x - 1

Answer 18

look at the graph

what is the slope of this line?

Answer 19

1/3 @jim_thompson5910

Answer 20

how are you getting 1/3?

Answer 21

sorry 9/2 rise over run
@jim_thompson5910

Answer 22

getting closer, but no

Answer 23

Im not sure then @jim_thompson5910

Answer 24

start at the first point, then what is the rise? what is the run? to get to the next point

Answer 25

Rise ;4 run 2 thats what I got @jim_thompson5910

Answer 26

it should be

rise = 6
run = 2


so the slope is what?

Answer 27

3/1 @jim_thompson5910

Answer 28

or just 3

Answer 29

now what is the y-intercept

Answer 30

1 right? @jim_thompson5910

Answer 31

where does it cross the y axis?

Answer 32

i'm not sure @jim_thompson5910

Answer 33

look at the graph

Answer 34

where does the diagonal line cross the y axis?

Answer 35

it crosses at 1 @jim_thompson5910

Answer 36

look again

Answer 37

the y axis is the vertical axis

Answer 38

I cant find it @jim_thompson5910

Answer 39

see attached (look at the red dot)

Answer 40

o ok -1 @jim_thompson5910

Answer 41

so that's the y-intercept

Answer 42

o so its y=3x-1 A.

Answer 43

correct

Answer 44

thanks
