Answer:

-7/4

Step-by-step explanation:

When you find the perpendicular slope, you take the opposite reciprocal of the original slope. For 4/7, the opposite is -4/7, and the reciprocal of that is -7/4.

Answer:

independent

Step-by-step explanation:

Since no one else answered,  figured you wouldn't mind if I do. :-), and you didn't use any CAPS.

How those two events (even and greater than 9) relate?

independent: YES. Can one happen without the other?  Certainly.  You see (1,1) is an even number that  is not greater than 9.  Equally, you see (6,5) which is greater than 9, but is not an even number.

inclusive: No, since  there's a least one case where a pair number is not greater than 9.  The opposite is also true... at least 1 number > 9 that is not even.

Mutually exclusive: No, since there numbers that are even AND greater than 9 (6,4) for example.

Conditional: No. Does one need the other to happen?  Absolutely not.
