Y = -2x -5
why?
-2x is found since in the table the x value is 0 and the y = -2
-5 because you are adding -5 every time
0= -2
-1 = -7
-2 = -12
-3 = -17
Answer:
-43 < -35
(Negative 43 is less than negative 35).
Looking at the two black dots
5 bulbs cost $9
Divide total cost by number of bulbs bought:
9 / 5 = $1.80 per bulb.
10 bulbs cost $18
Divide total cost by number of bulbs bought:
18 / 10 = $1.80 per bulb
The cost for one bulb is $1.80
ummmmmm you dont need the explanation and I'd rather not type but trust me its d, good luck!
