Question

Find the equation of the line with slope m=−13 and passing through the point (1,13).

Answer 1

@Angle

Answer 2

We have something called ` point-slope form `

` y = m(x - a) + b `

when
m is the slope
and the point (a, b) is a point on the line

Answer 3

y=-1/3(x-1) + 1/3

Answer 4

you got it :)

Answer 5

do I multiply by 5?

Answer 6

nope, we only did that last time because the standard form doesn't like fractions

Answer 7

but 1/3 and 1/3 are fractions

Answer 8

yes, but what we have is point-slope form

only the standard form doesn't like fractions
does your question want your equation in standard form?

Answer 9

Yep it has to be in standard form

Answer 10

ohhh
then yes, we want to multiply by the common denominator

so multiply by 3 this time

Answer 11

y=-1(x-3)+1

Answer 12

awesome!

then if we want standard form, we first want to distribute that -1 into the parentheses

Answer 13

y=(-1-3)+1

Answer 14

close
-1(x - 3)
=
-x + 3

Answer 15

y=(-x-3)+1

Answer 16

negative times negative becomes a positive

Answer 17

y=(x-3)+1

Answer 18

y = -x + 3 + 1

Answer 19

which simplifies to
y = -x + 4

then move the x to the other side

Answer 20

y=-4x

Answer 21

y=4x

Answer 22

x + y = 4

Answer 23

it's x + y = 4?!!???????????????!!!!!!

Answer 24

mhm

Answer 25

thanks for helping me I'm grateful for your help

Answer 26

@Angle its incorrect

Answer 27

ah I forgot to multiply the y by 3 as well

Answer 28

LOl

Answer 29

x + 3y = 4

Answer 30

thanks

Answer 31

it's x+3y=2

Answer 32

weird

Answer 33

lol
