Question

find the slope of each line
y-1=0

Answer 1

This is a horizontal: what is its rise/run?

Answer 2

what u mean

Answer 3

Slope is rise over run, right? So how many units does a horizontal line RISE per unit of the domain (don't worry about the size of this unit: the answer will turn out to be very simple)

Answer 4

i dont understand can u guide me through the steps please

Answer 5

I'm having some technical difficulties on my end, so, if you haven't already, draw a horizontal line. The definition of slope on a line with two points given is the difference of the y values over the difference of the x values. Just concentrate on the y values: do they ever change, or, since the equation can be rewritten as y=1, is the numerator of your slope equation going to be 1-1 or 0?

Answer 6

solve for y to get it in standard form y=mx+b

Answer 7

so do i subtract the y

Answer 8

well you want to solve for y so you can subtract the y from both sides and get -y=-1, then you would divide the negative or you can add 1 to both sides and get y=1

Answer 9

it's all the same I guess.

Answer 10

and that would be my answer

Answer 11

no

Answer 12

you're looking to make that equation into a familiar form.

Answer 13

for example if I had 2y-4x=2 I would want to solve for y to get y=2x+1

Answer 14

that's just like y=mx+b

Answer 15

so m=2 x=x and b=1

Answer 16

so once you get y=1, what do you notice?

Answer 17

let's pretend it's y=mx+1, what would m have to be to get y=1?

Answer 18

y=1x+0

Answer 19

not quite.

Answer 20

if y=1 and the standard form is y=mx+1 then mx=0, right?

Answer 21

yes

Answer 22

ok, now what does m have to equal to get that answer?

Answer 23

what times x would give you 0?

Answer 24

1

Answer 25

1*x=0?

Answer 26

0 times 0

Answer 27

0*x=0

Answer 28

right?

Answer 29

so m would equal to 0

Answer 30

yes.

Answer 31

so the slope is what?

Answer 32

0

Answer 33

yes!

Answer 34

so how should i write it out

Answer 35

well the slope of y-1=0 is 0

Answer 36

so zero would be my slope

Answer 37

yes. :)

Answer 38

thanks

Answer 39

no problem.
