On a map of Chicago, 1 cm represents 100 m. Select all statements that express the same scale. Select all that apply:
5 cm on the map represents 50 m in Chicago
1 mm on the map represents 10 m in Chicago
1 km in Chicago is represented by 10 cm on the map
100 cm in Chicago s represented by 1 m on the map.

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)

m∠a is 90°

m∠b is 40°
