-1,4

-2,2           0,2
                  0,1

well, your points are relatively ploted as this.

they do not form a line, unless youve erred in writing them

the slope can be assumed of its a graph by determing how high it is, with regards to how far it moves.

if the line moves thru the origin,  then we simply choose a convenient point on the line
