Solution

We can find the quations for each slope in the following way:

(-3,-1) (0,1)


m=(1-(-1))/(0-(-3))=(2)/(3)

1 = 2/3 (0) +b

b= 1

y = 2/3 x +1

For the second case we have:

(-2,6) and (0,0)


m=(0-6)/(0+2)=-3

0=-3(0)+b

b=0

y= -3x+0

And taking in count the info given the best solution is:

(-1,3)
