Describe the pattern. that does not make sense to me at all

The pattern is multiplying by 2

Step-by-step explanation:

.41, .82,1.64,3.28,

Take the second term and divide by the first term

.82/.41 = 2

Take the third term  and divide by the second term

1.64/.82 = 2

Take the fourth term and divide by the third term

3.28/1.64 = 2

We are multiplying by 2 to get from the first to the second term, the second to the third term, the third to the fourth  term.  

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)
