Why an i bad at this someone explain steps

well the answer

Step-by-step explanation:

is 16(0.5x-0.75y+2)

THIS is because 16×0.5=8

16×0.75=12

16×2=32

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
