Answer: (1,4)
Step-by-step explanation:
Given
Equation of line is 
(-1,1) is the solution of the equation
Take x=1 and substitute it in the above equation

So, another pair of the solution is (1,4)
(15, -8) :)
From C to midpoint you do (+10, -7), so you have to do that again to get to D
Answer: 5/2
5/6 / 1/3 = 2.5
2.5 in fraction = 5/2
The answer to the question is (2,-2) d
Since it's a multiple of 24, it has to be a multiple of the factors of 24.
Factors of 24:
2,3,4,6,8,12
You can use some of this knowledge to help create the number.
Since the # needs to be a multiple off 2, the last digit needs to be an 8
All numbers that are multiples of 3 have the property that all of their digits added together have to be a number that is evenly divisible by 3.
so your number will look like:
_ _ _ _ _ 8
so start trying combinations for the other 5 digits that give you a number that is a multiple of 3: 3,6,9,12,15, ect. If you can't find one, then it's impossible
