Select the correct answer from each drop-down menu. Last year, sales at a book store increased from $5,000 to $10.000. This year, sales decreased to $5,000 from $10.000. What percentage did sales
increase last year? What percentage did sales decrease this year?
Sales increased 100% last year, from $5.000 to $10,000. When sales dropped from $10,000 to $5,000 this year, sales decreased

c

step-by-step explanation:

because of the levels

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)
