Which is the equation of a line perpendicular to the line with the equation: Y=-1/4x+7 A. y=-4x-7
B. y=4x+2
C. y=1/4x-1/2
D. y=-1/4x+3​

The answer is 42

Step-by-step explanation:

I might be doing this wrong, but if we multiply 40 by 30 to find the total area of the country (1,200 square miles), we can divide the total population (50,000) by each answer choice to find which answer is correct; 50,000/42 is equal to 1,190, the closest product to 1,200. I claim to have possibly done this wrong, but 42 was the correct answer I received on the quiz -- hope I helped!
