What is the absolute value of difference between each value and mean O 1,7,4,11,4,9,5,1
O 5.25,6.25,7.25,8.25,10.25,11.25,12. 25

i think it is 18

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

x = -5
