In the coordinate sysptem above (please see og 11 p. 183), which of the following is the equation of line L?

a.2x-3y=6
b. 2x+3y=6
c. 3x+2y=6
d.2x-3y=6
e.3x-2y=-6


qa is b however my computations are a bit off!

i got --- y=-2/3x+2 --->3y=-2x+2------>2x+3y=2

I dont see how the 6 comes into play here? i distributed the right way.. hmm?
Appetite for 700 and I scraped my plate!

y=-2/3x+2

Multiply both sides by 3

3*y = 3*(-2/3x+2)
3y=-2x+6
