average rate of change = slope
so x=-1 y= 5 x=4 y=-5
Where is the 5 from
you just read it of your y axis
So how do you find the slope? -5-5 and 4-1?
you got a formula for that
Thats what i did so what is y2 and y1
you got two points found . so you take a value for x1 so we can take x1=-1 so y1= 5 right?
So its -2?
Ya i solved it and got -2
then we fill in our other coordinates. x2=1 and y2 =-5
yes lol :p
sorry i was afk
anyhow you just fill in your twoo coordinates you found (x1,y1) and (x2,y2) in your formula
So it would be -5-5 which is -10 than 4- neg 1 which is 5 and you divide it than you have -2?
Its ok Nnesha
Ok thank you yall
remember that you now have the slope but if u want an equation for this line the formula is y-y1=m(x-x1) and m is your slope you just calculated
I just wanted the slope and ya you use standard equation form for the equation. Thx
I mean point slope
yes but it's very important to see the whole picture! :)
Can you helo me with another one?
sure if i can :)
Ok i will do it on new thread
