Christian earns 15% for each chocolate bar that he sells while working at his Grandmother's candy shop.

a) If he sells chocolate bars for $1.50, what is his commission (his earnings..
the 15%)?

b) How much did Christian earn when he sold 30 chocolate bars?

(This is not a multiple choice question)

(-6,0)(-3,-1)
slope = (-1 - 0) / (-3 - (-6) = -1 / 3

y = mx + b
slope(m) = -1/3
(0,-2)...x = 0 and y = -2
sub and find b, the y int
-2 = -1/3(0) + b
-2 = b

so ur equation is : y = -1/3x - 2u got it right...and u did get -2 as the y int...because in y = mx + b form, the number in the b position is ur y int
