Fred had a garden. The number of flowers in the garden can be determined by the equation: F= 2b, where F is the number of flowers and b is the number of bulbs Fred has planted. Find the constant of proportionality.

Constant of proportionality = 2

Step-by-step explanation:

F = 2b (given)

This indicates that F is directly proportional to b

That is, F ∞ b

Removing the proportionality sign, F = kb where k is the constant of proportionality.

Comparing this with F = 2b, we have that k = 2

d

step-by-step explanation:

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)
