Which ratio expresses the scale used to create the drawing?

The school has dimensions of 18 feet by 18 feet.

a. 1 square/3 feet = 18 feet/6 squares
b. 1 square/3 feet = 6 squares/18 feet
c. 3 squares/1 foot = 18 feet/6 squares
d. 3 squares/1 foot = 6 squares/18 feet

B

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)

answer: (1,3) (3,-1) (5,-5) ?
