The length of a room is twice its breadth and thrice its height. If the cost of carpeting the floor at Rs 80 per sq. metre is Rs 9000, find the cost of plastering its walls and
ceiling at Rs 35 per sq. metre.

answer: answer

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

won't that be plagrisim thought?
