Can someone please answer this? Thank you

1 63/80 or 1.7875

Step-by-step explanation:

2/4 + 18/5 + 28/10 + 5/20

First find a common denominator (20)

10/20 + 72/20 + 56/20 + 5/20 = 143/20

Then you divide that by 4 which is the number of the set of numbers you are given.

(143/20)/4= 1 63/80

1 63/80 or 1.7875

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

and?
