Answer 2

Last question @iGreen.

Answer 3

\(y - y_1 = m(x - x_1)\)

Where y1 is the y-value of the point, x1 is the x-value of the point, and 'm' is the slope.

Answer 4

It gives you the point (2, 8).

So x1 here is 2, and y1 here is 8. Can you plug that into point-slope form?

\(y - y_1 = m(x - x_1)\)

Answer 5

Can you do it?

Answer 6

y= 2 x=6?

Answer 7

x1 = 2, y1 = 8

Answer 8

oh woops XP

Answer 9

Try again.

Answer 10

(6,0)

Answer 11

It gives you the point (2, 8).

So x1 here is 2, and y1 here is 8.

\(y - y_1 = m(x - x_1)\)

\(y - 8 = m(x - 2)\)

Now let's find the slope..

Answer 12

Take any two points:

(6, 0) (2, 8)

Plug them in:

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

\(m = \dfrac{8-0}{2-6}\)

Simplify

Answer 13

(8,-4)

Answer 14

Yes, so the slope is -8/4, simplify it.

Answer 15

Just divide -8 / 4

Answer 16

-2

Answer 17

Yes, so our final answer is

\(y - 8 = -2(x - 2)\)

Answer 18

thank you again :P

Answer 19

No problem :P
