(20x^2+5x-19)/(5x-5) how do I explain this

is there any photos or whatever?

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+4 would be the answer
