do you know the formula?

I learned it in ninth grade and I really don't remember it, but if you show me it, I'm sure I can remember some of it.

11-12/6-2?
Liv1234
  • Liv1234
Would the answer be A? -1/4? And could you help me with a similar one just to make sure I did it right?
Mehek14
  • Mehek14
correct and sure
Liv1234

what did you get?
Liv1234
  • Liv1234
I'm putting the numbers into the formula right now to see.
Liv1234
  • Liv1234
-1-1/-3-6?
Liv1234
  • Liv1234
I think the answer is undefined.
Mehek14
  • Mehek14
-1 - (-1)/ -3 - 6
Liv1234
  • Liv1234
0/-9
Mehek14
  • Mehek14
-1 - (-1) = 0 -3 - 6 = -9
Liv1234
  • Liv1234
So, is the answer zero?
Mehek14
  • Mehek14
yup undefined = when the denominator = 0
Liv1234
  • Liv1234
Thanks! Could you help me with another one?
Mehek14
  • Mehek14
yup

Is the formula for slope intercept form "A + B = C"
Mehek14
  • Mehek14
\(\bf{y=mx+b}\) m = slope b = y-intercept
Liv1234
  • Liv1234
I'm having trouble deciding what the line goes through :/
Mehek14
  • Mehek14
ok so look at the y-intercept at what point does it cross the y-axis?
Liv1234
  • Liv1234
At 2?
Mehek14
  • Mehek14
so b = 2 \(\bf{y=mx+2}\)
Mehek14
  • Mehek14
so either C or D
Mehek14
  • Mehek14
both have the slope 2
Mehek14
  • Mehek14
but 1 is -2 one is 2
Liv1234
  • Liv1234
I think it's C because it's in the negative
Mehek14
  • Mehek14
line is going up
Liv1234
  • Liv1234
So, D? Because since the line is going up, it has to be in the positives?
Mehek14
  • Mehek14
so postive
Mehek14
  • Mehek14
yes D
Liv1234
  • Liv1234
Can you help me with another one? I appreciate your help.
Mehek14
  • Mehek14
ok
Liv1234
  • Liv1234
Liv1234
  • Liv1234
Mehek14
  • Mehek14
change to y =mx + b \(\bf{y=5x-3}\)
Mehek14
  • Mehek14
y-intercept -3 so A or B
Mehek14
  • Mehek14
positive slope so B
Mehek14
  • Mehek14
I mean A
Liv1234
  • Liv1234
So the answer is A? And can you help me with one more, I promise it's the last one.
