Kimberly has 80 coins in her collection she shared 1/8 of her collection equally between two friends how many coins did each friend receive

1/8 of 80 is ten divide ten by two you of her get 5 that is how many coins each of her two friends get

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
