Start by finding the starting point where does the line touch on the y axis?

I honestly have no clue. I dont know anything about functions or graphs.

Looking for something else?

Nawh i prefer to help you no matter what it takes :) let's start of with the basics |dw:1449531766772:dw|

So we have a graph labeled with 2 axis' x and y in the equation y=mx+b m is the slope and b is the y-intercept understood? So far?
anonymous
  • anonymous
yeah, I understand the concept of it all, but its just the numbers that make me confused.
pooja195
  • pooja195
Ok basically the y intercept is the starting point of the line
pooja195
  • pooja195
|dw:1449531912992:dw| See where i labeled that dot?
anonymous
  • anonymous
Yeah.
pooja195
  • pooja195
that is where the line was touching the y axis so the b part of our equation is -2 Do you get it?
anonymous
  • anonymous
Yes.
anonymous
  • anonymous
so b can be crossed out
pooja195
  • pooja195
Correct Any ideas on how to find the slope?
anonymous
  • anonymous
sadly, nope
pooja195
  • pooja195
Alright that's fine Slope=rise/run If it's a negative slope then you count down Here look |dw:1449532203598:dw| Basically you pic a random point in which the line goes through and see how you can get to the next point can you figure out the slope with the drawing i provided?
anonymous
  • anonymous
Im still very confused but I do see your point sorta. and imma say I think its C.
pooja195
  • pooja195
C is correct lol I suggest looking at this http://www.mathsisfun.com/geometry/slope.html
