To find the slope given two points you would use this equation: \[\frac{ x _{2}-x _{1} }{ y _{2}-y _{1} }\] So for this problem you would set it up as: \[\frac{ 1-(-2) }{ 4-5 }\] This can be simplified to solve easier. \[\frac{ 1+2 }{ 4-5 }\] Now you solve this to find the slope of the line through those two points.

Ok well if you solve the last fraction I gave you, it would end up that the slope is \[-\frac{ 3 }{ 1 }\] But this can be simplified to be just -3.
