(3-5)/(3-0) = -2/3 remarkable

(1-3)/(6-3) = -2/3

just for sport

(1-7)/(6-(-3)) = -6/9 = -2/3 how do you like that? It might be a straight line through those points with slope = -2/3

Try one of those points in

y = -(2/3)x + b

7 = (-2/3)(-3) + b

7 = 2+b

b = 5

so

y = -(2/3) x + 5 goes through all points I believe

Try it in the last point

1 = -(2/3)(6) + 5 ?

1 = -4 + 5

1 = 1 , sure enough, done

- Get it ? -
