m(slope)= change in y/change in x
m=-17-(-5)/3-1
m=17+5/2
m=22/2
m=11
Answer:
c = $7n + $6
Step-by-step explanation:
$6 shipping for any size
$7 per necklace
let n equal the quantity of necklaces and c equal the total cost.
you buy n amount of necklaces and add the shipping cost to find your cost.
I think the answer is 9.3, but I’m not sure
This can be solved using a system of equations.

Subtract y from both sides.

Substitute:

Subtract 80 from both sides:

Divide both sides by 5:

Substitute.
3m-10=2(4m-5)
3m-10=8m-10
3m-8m=-10+10
-5m=0
m=0
