yes

Can you help me please?(:

do you know the formula?

\(\bf{\dfrac{y_2-y_1}{x_2-x_1}}\)

I remember the formula, I'm just trying to remember how to put the numbers in. And thanks! (:

6-2/11-12?

:)

|dw:1443210781657:dw|

11-12/6-2?

correct and sure

Thanks!

what did you get?

I'm putting the numbers into the formula right now to see.

-1-1/-3-6?

I think the answer is undefined.

-1 - (-1)/ -3 - 6

0/-9

-1 - (-1) = 0
-3 - 6 = -9

So, is the answer zero?

yup
undefined = when the denominator = 0

Thanks! Could you help me with another one?

yup

Is the formula for slope intercept form "A + B = C"

\(\bf{y=mx+b}\)
m = slope
b = y-intercept

I'm having trouble deciding what the line goes through :/

ok so look at the y-intercept
at what point does it cross the y-axis?

At 2?

so b = 2
\(\bf{y=mx+2}\)

so either C or D

both have the slope 2

but 1 is -2
one is 2

I think it's C because it's in the negative

line is going up

So, D? Because since the line is going up, it has to be in the positives?

so postive

yes D

Can you help me with another one? I appreciate your help.

ok

change to y =mx + b
\(\bf{y=5x-3}\)

y-intercept -3
so A or B

positive slope so B

I mean A

So the answer is A? And can you help me with one more, I promise it's the last one.
