Question

[4.06]What is the equation of the line that passes through the points (−1, 3) and (1, 11)?

4x − y = 1

4x + y = 1

x − 4y = −13

4x − y = −7

Answer 1

Answer 2

Point-slope form is classic.

Answer 3

\[\rm y-y_1 = m(x - x_1)\]

Answer 4

I found for the slope 4

Answer 5

is that correct?

Answer 6

Yes!

Answer 7

the point slope ofrm is y-11=4x(x-1)

Answer 8

correct?

Answer 9

sorry 4(x-1)

Answer 10

\[\rm y - 11 = 4(x - 1)\]Yes!

Answer 11

yap correct

Answer 12

then when i solve it gives me y=4x+7

Answer 13

correct?

Answer 14

Right!!

Answer 15

then i have trouble can you walk me through it?

Answer 16

Yes, I will.

You have to get all variables on one side.

Answer 17

how

Answer 18

show me please?

Answer 19

Subtract \(\rm 4x\) from both sides.

Answer 20

so it gives me -4x-y=7

Answer 21

?

Answer 22

No...\[\rm y = 4x + 7\]\[\rm y - 4x = 4x - 4x + 7\]

Answer 23

these are my options for the answer

4x − y = 1

4x + y = 1

x − 4y = −13

4x − y = −7

Answer 24

The options are wrong. ;)

Answer 25

Or, if you need it, try plugging in values.

Answer 26

no the options are correct I assure you

Answer 27

\[\rm 4(1) - 11 = 1 \]the first option is not right.

Answer 28

may you just give me the answer?

Answer 29

\[\rm 4(1) + 11 = 1\]not right either

Answer 30

\[1 - 4(11) = -13\]no

Answer 31

is it the 4 one

Answer 32

\[4 - 11 = -7\]

Answer 33

Yes.

Answer 34

thanks

Answer 35

@ParthKohli can you help me with 2 others?
