**Dr Russ**, Monday, June 6, 2011 at 9:59amIf it is linear then the general equation for a straight line

y=mx+c

must apply

Take two sets of coordinates and plug these in

-5=-2m+c

-2=-1m+c

solve for m and c

m=3

c=1

check using another set of points

7=2x3+1 which is fine

so equation is

y=3x+1
