Question

Please Help! Find the value of y so that the line passing through (4, y) and (5, 3) has a slope of 1
If someone could provide a short explanation on how to do it to, I'd be greatful..

Answer 1

m = (y2 - y1)/(x2 - x1)

1 = (y2 - y1)/(x2 - x1)

1 = (3 - y)/(5 - 4)

solve for y

Answer 2

i dont undertand :(

Answer 3

I'll keep going

1 = (3 - y)/(5 - 4)

1 = (3 - y)/(1)

1*1 = 3 - y

1 = 3 - y

y = ???

Answer 4

I'm just using the slope formula, then plugging in what we're given to find the unknown value

Answer 5

............

Answer 6

where are you stuck?

Answer 7

all of it...

Answer 8

the slope formula is m = (y2 - y1)/(x2 - x1)

look familiar?

Answer 9

yeah, I have the formula with me right here.

Answer 10

ok great

Answer 11

the given slope is 1, so m = 1

Answer 12

which is why I went from

m = (y2 - y1)/(x2 - x1)

to

1 = (y2 - y1)/(x2 - x1)

Answer 13

okay i understand a bit now..

Answer 14

then I plugged in the given points

Answer 15

(x1,y1) is the first point

the first point is (4,y)

so you replace x1 with 4 and y1 with y

----------------------

(x2,y2) is the second point

the given second point is (5,3), so you replace x2 with 5 and replace y2 with 3

Answer 16

all of those substitutions give you

1 = (3 - y)/(5 - 4)

Answer 17

and from there, you solve for y

Answer 18

....... okay..

Answer 19

so are things clearer?

Answer 20

a bit

Answer 21

alright keep practicing and hopefully they'll get even more clearer

Answer 22

i still dont know the answer ;___;

Answer 23

1 = (3 - y)/(5 - 4)

1 = (3 - y)/(1)

1 = 3 - y

y = ____ ... fill in the blank

Answer 24

i give up

Answer 25

3 - NUMBER = 1

NUMBER = ???

Answer 26

1...?

Answer 27

no

Answer 28

oh....

Answer 29

3-y = 1

3 = 1+y

3 - 1 = y

2 = y

y = 2

Answer 30

i feel stupid... thank you though for tryingtoexplain it to me..

Answer 31

no you're not stupid, so don't ever think that

Answer 32

you just don't have enough practice

Answer 33

okay, thanks

Answer 34

yw, keep practicing
