Pepino’s pizza charges $8 for medium pizza plus $2 for each topping. How many toppings are on a medium pizza that costs $20?

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
