princeharryyy · Answer

use (y2-y1)/(x2-x1)

anonymous · Answer

Well, to find the slope of a line, you must follow this equation:
$$\frac{ y _{2} - y _{1} }{ x _{2} - x _{1} }$$

princeharryyy · Answer

(-5+1)/(-2-3) = 4/5

anonymous · Answer

Plug it in:
$$\frac{ -5 - (-1) }{ -2 - 3 }$$

anonymous · Answer

It'd actually be $$\frac{ -4 }{ 5 }$$

princeharryyy · Answer

-4/(-5) = 4/5 @kybi

anonymous · Answer

Yes it is 4/5 
Correct @princeharryyy

anonymous · Answer

Hm, true. Sorry, I made a slight error with the negatives

anonymous · Answer

Thank you @princeharryyy :)

anonymous · Answer

Sorry for the wrong-ish answer xD

princeharryyy · Answer

no problem @kybi

anonymous · Answer

it's fine @kybi thank you for trying :)

anonymous · Answer

Assuming the points are (0,2) and (5,0) and that the "-" is used as a separator rather than as a minus sign. If it is a minus sign, why -0?

Slope = difference in y coordinates/difference in x coordinates 
= (2 - 0)/(0 - 5) = 2/(-5) = -0.4
