## anonymous 5 years ago find the slope if is exists to the pair containing the pair of points (-4,-10) and (-5,-11)

I think the first 'pair' should be 'line' ? Do you know the formula for the slope of a line given two points?

2. anonymous

I am not sure

3. anonymous

$Slope = {y_2 - y_1 \over x_2 - x_1}$ Where (x1,y1) is one point and (x2,y2) is the other point.

this is what I was doing, (-4,-10)(-5,-11) Subtract 10 from -4, to get -14. (-14)(-5,-11) Subtract 11 from -5, to get -16. (-14)(-16) Multiply -14 by -16 to get 224. (224) Remove the parentheses around the expression 224. 224

so is it completely wrong

6. anonymous

you want the change in y divided by the change in x. y starts at -10 and goes to -11 so it has changed -1. x starts at -4 and goes to -5 so it changes by -1. Then you have -1/-1=1

dvl im not sure exactly what you were doing

8. anonymous

I'm pretty sure this is some kind of math troll. He's trying to multiply the x part of the point to the y part, then multiply those two products together.

9. anonymous

Which is nothing like what I said.

yeah i'm very confused. Well you gave the correct formula so nothing else to do.
