Question

Solve the Equation

Answer 1

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

Add \(y1\) to both sides:

\(m + y_1 = \dfrac{y_2}{x_2-x_1}\)

Multiply \(x_2-x_1\) to both sides:

\(y_2 = (m + y_1)(x_2-x_1)\)

Answer 2

I think that's right..

Answer 3

Oh wait..I think it's:

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

Answer 4

I'm confused..@ganeshie8

Answer 5

no no @iGreen you're right :)
y2 = y1 + m(x2 - x 1)

Answer 6

Okay, thanks @PFEH.1999

Answer 7

you're welcome ;)

Answer 8

Thank you for explaining it as of right now im looking it over @iGreen

Answer 9

Okay.

Answer 10

@iGreen

Answer 11

Okay..hold on. I'm not that good at word problems..

Answer 12

He travels 65 MPH

It takes 1 hour and 30 minutes to get to work.

Car travels at 25 miles a gallon

Gas costs 3.65 a gallon

Answer 13

$3.65 for 25 miles.

Answer 14

65 miles per hour:

1 hour and 30 minutes:

1 hour = 65 miles

30 minutes is half of an hour.

And half of 65 is 32.5

So he travels 97.5 miles to go to work.

Answer 15

14.0

Answer 16

14.60 sorry

Answer 17

Gasoline costs $3.65 a gallon.

1 gallon = 25 miles

It takes him 97.5 miles to go to work.

97.5 / 25 = 3.9.

3.9 gallons.

3.65 * 3.9 = $14.24

Answer 18

Lol it's around that..
