The driving distance from the sports arena to kristina's house in 10 9/10 miles. the distance from the sports arena to luke's house is 2 7/10 miles. how much greater is the driving distance between the sports arena and kristina's house than between the sports arena and luke's house?

  8.2 miles

Step-by-step explanation:

  (arena to Kristina's house) - (arena to Luke's house) = 10.9 - 2.7

  = 8.2 . . . miles

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)

i think it might be a but you might want a second opinion
