A(-1;14), x=-1, y=14
B(2;-10), x=2, y=-10
General equation for linear function is 
Let's solve system of equations

If one inch represents 15 feet, then:
2 inches represent:
2 * 15 = 30 feet
1 2/3 inches represent:
1 2/3 * 15 =
= 5/3 * 15 =
= 75/3 =
= 25 feet
So the real area of the court is 30 * 25 = 750 square feet.
You would have no trouble at all if the problem said "11 cows - 8 cows",
or "11 books - 8 books", or "11 cats - 8 cats", or "11 footballs - 8 footballs".
So why does it scare you when the items being counted are 'm's ?
Oh ! Here's another beauty: 11 M&Ms - 8 M&Ms = ?
We need 2880 person-hours and we have 12 people.
When we divide the work between them: 2880/12 = 240 hours required to complete.
Answer: 40
Step-by-step explanation: -5 x -8 is 40 since the negatives cancel each other out, the product is positive :)
