Question

which equation represents the line that passes through the points (6,-3), (-4,-9)?

Answer 1

Start by finding the slope
\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]

Answer 2

the slope would be 6/ 1

Answer 3

How did you get that?

Answer 4

i am getting confused

Answer 5

Ok let's do this step by step :-)

\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]
\[\LARGE \frac{-9--3}{-4-6}=slope\]
\[\LARGE \frac{-9+3}{-4-6}=slope\]

Answer 6

is it wrong?

Answer 7

It is.

Answer 8

so it is -6/-10

Answer 9

Yes simplfy it

Answer 10

the negatives cancel out so it is 6/10 and the simplest form is 3/5

Answer 11

Correct :-)
Now are we making an equation in slope intercept form or point slope?

Answer 12

point slope form

Answer 13

Ok
so we have the slope
and 2 points given
\[\huge y-y_1=m(x-x_1)\]
where
m=slope
(x1,y1)

Answer 14

so the equation is y+3=3/5(x-6)

Answer 15

Perfect!
