3/5
2-(-3)=5
7-4=3
slope should be 0.6 (3/5)
L(-8,3),K(4,1) and M(-1,-4)
Hopes this helps.
A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
