Calculate the area of triangle abc with altitude cd, given a(6,-2) b(1,3) c(5,5) d(2,2) a: 12 square units b: 13 square units c: 14 square units d: 15 square units

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
