Question

Write equation of the line in slope intercept form that passes through the two points

(-6,-3) (-8,4)

Answer 1

Easy, find the slope. then plug that into the point-slope formula and solve.
\[ {\big \smile } \]

Answer 2

again slope=-7/2
so equation of line is y=-7/2x-24

Answer 3

Ignore that "big smile" thing xD

Answer 4

lol big smile

Answer 5

@quantun I hope you aren't doing the users work for them

Answer 6

the slope is -7/2 so i take one of those points and plug them in for y and x in the formula

Answer 7

Correct.
I'm sure you already know how he found the slope right?

Answer 8

yes y2-y1/x2-x1

Answer 9

Good :)

Answer 10

kk so it should look like 4=-7/2*8+b

Answer 11

Where are your x and y's?

Answer 12

o shoot i wrote it wrong

Answer 13

lol

Answer 14

4=-7/2 -8+b
y=mx+b
is that right?

Answer 15

First you use the point slope formula, then you change it to slope-intercept form

Answer 16

\[y-y1=m(x-x1)\]

Answer 17

75.6

Answer 18

wait i thought we already had the slope -7/2

Answer 19

Let's start again please :-)

Answer 20

Yes, now just plug the slope and any point you choose into the equation.

Answer 21

o lol

Answer 22

so y- -3=-7/2(x- -6)

Answer 23

Yes, now just simplify :)

Answer 24

kk

Answer 25

y- (-3)=-7/2(x- (-6))

Answer 26

i got y-(-3)=-7/2x+21
is that right and i just add the 3 to both side get rid of it right?

Answer 27

Hm, you made an error with your signs.

Answer 28

o it should be a negative 21

Answer 29

Yup, and when you have a --, it'd be easier to just change them into a + right away so it doesn't confuse you

Answer 30

o kk lol so make the negative 3 a positive 3 and subtract from both sides

Answer 31

Bingo!

Answer 32

i got y=-7/2+8

Answer 33

it will be -24

Answer 34

8? xD

Answer 35

Oh Miss Jessica :3

Answer 36

lol i was typing to fast and hit 8 sry

Answer 37

i meant -24 :)

Answer 38

Hm, well alright Good job!

Answer 39

Answer 42

lol what is that

Answer 43

O thx XD

Answer 44

its really cool
