I need some Math help please....
Indicate in standard form the equation of the line passing through the given points.
R(3, 3), S(-6, -6)

lgbasallote · Answer

use the formula $$\Large y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)$$
does that help?

anonymous · Answer

I got...
Y-3=-9 over 9=X-3

lgbasallote · Answer

close...
$$\Large \frac{y_2 - y_1}{x_2 - x_1} \implies \frac{-6 - 3}{-6 - 3} \implies \frac{-9}{-9} \implies 1$$
so the equation should be something like

y - 3 = 1(x-3)

do you get it?

anonymous · Answer

Yeah. So that's the answer?

lgbasallote · Answer

not yet. simplify it

anonymous · Answer

Now I'm lost. I have no idea how to simplify it.

lgbasallote · Answer

what's 1(x-3)?

anonymous · Answer

I don't know. Distributive property?

lgbasallote · Answer

yup

anonymous · Answer

So.. is the answer 1x-3?

lgbasallote · Answer

right..

y - 3 = x- 3

now add 3 to both sides

anonymous · Answer

Alright man, thanks I appreciate the help!
