find the slope of a line that passes through (-2 -3) and (1 1).

mathmale · Answer

Look for the formula for "slope of a straight line."  I'd bet you've seen and used this before.  Find the slope of the line thru the given points, showing all work, please.

m=y2-y1 over x2-x1 ? I'm not sure how to set it up like which numbers goes where..

You are given two points:   (-2 -3) and (1 1)
Either one could be regard as Point #1 and then the other regarded as Point #2.
If Point #1 is (-2,-3), then x1 = -2 and y1=-3.

Tray again.   Find the slope of the line connecting these two points.

-3-(-2) = -1 so would the slope be -1?

anonymous · Answer

oh wait but then there is (1,1) okay i will do that one aswell

anonymous · Answer

1-1=0 so -1?? @mathmale

mathmale · Answer

Please show your work.   

Use the formula for the slope:  $$m=\frac{ y-y _{1} }{ x-x _{1} }$$

First, identify which point is Point#1 and which is Point #2.

You are correct here:  "m=y2-y1 over x2-x1 ? I'm not sure how to set it up like which numbers goes where.."
