Answer:
the record holder is 1260 with 36 factors.
Step-by-step explanation:
Plug the values into point slope and simplify
y-4= 4(x-(-2))
y-4= 4x+8
y= 4x+12
Final answer: y=4x+12
Equation = a² + b² = c²
a = 80
b = 39
c = Diagonal
a² + b² = c²
80² + 39² = c²
6400 + 1521 = c²
c² = 7921
c = √7921
c = 89
Answer = 89 units
