8.2g of sugar is needed for every cake made. How much sugar is needed for 12 cakes?

98.4

Step-by-step explanation:

Since one cake equals 8.2 g of sugar, we can multiply this by 12 to get 12 cakes equals 98.4 g of sugar

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)
