From the diagram above you can see that points A and B have coordinates (8,0) and (-4,6), respectively.
The equation of the line passing through the pointa A and B is:
Then
Answer: 
So 3+1=4 then you do the half you know 2 hlafs=whole so thats 1 and 4+1=5
5 is the answer
Answer:
The original price of the laptop is 840
Step-by-step explanation:
Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.
Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714
Now, we remember he was also given 15% off. Let the price paid be x;
The 15% of x is equal the difference between x and the 714
Thus;
15/100 * x = x - 714
15x/100 = (x-714)
15x = 100(x-714)
15x = 100x -71400
100x-15x = 71400
85x = 71400
x = 71400/85
x = 840
