Pia printed a map of a walking trail. the length of the trail on the map is 8 cm. (scale: 1 cm on the map represesents 2 km on the actual trail.) what is the length of the actual trail?

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)

not sure but it may be b, as i said i'm not sure.

yes   because as the functions are graphed they eventually will intersect unless otherwise
