If we write a line in the form
Then the coefficient m is the slope of the line.
Two lines and are:
- Parallel if
- Perpendicular if
The first line is already in the required form: . We deduce that its slope is 9.
Let's rewrite the second line in the required form:
So, its slope is -1/9.
9 and -1/9 are obviously not equal, so the lines are not parallel.
But their product is -1, which means that the lines are perpendicular.

Explicación paso a paso:
Dado que:
Kilogramo total de mandarina = 9 kg
Tamaño de cada distribución = 3/4 de kilo
Número de mallas:
Kilogramo / tamaño total por distribución
9 kg ÷ 3/4 kg
9 * 4/3
= (9 * 4) / 3
= 36/3
= 12
