Y-y1=m(x-x1)
slope=m
point is (x1,y1)
slope=3
point is (-6,-1)
y-(-1)=3(x-(-6))
y+1=3(x+6)
y = ( 3 * x ) - 2.
This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.
Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.
I think the answer is C, I hope this helps you!
