Question

Use the slope formula to find the missing coordinate.
R(0, _), S(-4, 2) m = 5

Answer 1

@MARC_

Answer 2

\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 3

Hello there, Welcome to OpenStudy! @kristyb056

Answer 4

The slope formula is

\(\sf Slope=\Large\frac{y_2-y_1}{x_2-x_1}\)

Where \(\sf (x_1,y_1), (x_2,y_2)\) are the two points.

Answer 5

\[5=\frac{ 2-y_1 }{ -4-0 }\]

Answer 6

\[5=\frac{ 2-y_1 }{ -4 }\]

Answer 7

so jow do i find y1?

Answer 8

how*

Answer 9

first,multiply -4 on both side

Answer 10

So you are given two points,

\(\sf (0, _-), (-4,2)\)

And so then
\(\sf x_1 = 0 \\ y_1= _- \\ x_2 = -4 \\ y_2=2\)
And we are looking for \(\sf y_1\)

Answer 11

\[5(-4)=-4(\frac{ 2-y_1 }{ -4 })\]

Answer 12

I will let @MARC_ continue on helping you as I do not want to confuse you with two people talking at the same time.

Answer 13

\[-20=2-y_1\]

Answer 14

so would i subtract both sides?

Answer 15

add?

Answer 16

\[y_1=2+20\]

Answer 17

y1=22?

Answer 18

yep

Answer 19

So thats the answer? Thank you!

Answer 20

yup :)

Answer 21

yw

Answer 22

Find the slope of the line that contains the points named.
X(2, -1), Y(0, 4)

Answer 23

would it be (2-0)(-1-4)

Answer 24

nope

Answer 25

\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 26

substitute the given values into the equation

Answer 27

(0+1)/(4-2)

Answer 28

(2,-1)(0,4)\[(x_1,y_1)(x_2,y_2)\]

Answer 29

ugh i keep getting that missed up

Answer 30

\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\] plug in the given values into this equation

Answer 31

\[=\frac{ 4-(-1) }{ 0-2 }\]

Answer 32

2.5?

Answer 33

you can just leave the answer in fraction form

Answer 34

Find the slope of the line that contains the points named.
J(1, -4), K(3, -1)

Answer 35

(3-1) (-1-4)
