Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.
Answer: this is the right answer Graph A represents j(x). The y-intercepts for f(x) and g(x) can be 1 and 3. And The rate of change of the sum of f(x) and g(x) is greater than that of either function. your welcome
