  1 7/8 quarts

Step-by-step explanation:

As you already know, the amount of grape juice required is 1/2 the amount of sparkling water.

  (1/2)(3 3/4) = (1/2)(15/4) = 15/8 = 1 7/8

1 7/8 quarts of grape juice are required.

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)
