step-by-step explanation:

answer: you need the equation in the question so i can answer it

step-by-step explanation:

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

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)
