Answer:
21
Step-by-step explanation:
(4,12)(5,15)
slope = (15 - 12) / (5 - 4) = 3/1 = 3....so the slope is 3
y = 3x...slope here is 3 as well
they have the same slope
Answer:
$4.30
Step-by-step explanation:
First, find the cost of both games by multiplying the price by 2:
7.85(2)
= 15.7
Then, to find his change, subtract this from 20:
20 - 15.7
= 4.3
So, Luke should get $4.30 back in change.
The slope is found as follows:
The answer is: slope = -4.
