Describe the symbolic representation used to transform C(15,18) to C’(5,6)

okay wait before i answer, is this for your points on a graph?

its a straight line parallel to the time axis

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
