Зr + 5 > Зr - 2
I think r could be anything but I'm not sure ​

Infinitely many solution.

Step-by-step explanation:

1) Cancle 3r on both sides.

2) Since 5 > - 2 is always true, there are many solution.

Infinitely many solution.

b

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
