Given the sets: A = {1, 2, 3, 6, 7, 9} and B = {2, 4, 6, 7, 8}. Find (A*upside down U*B). O A. {1, 4, 8, 9}
OB. {1, 2, 2, 3, 4, 6, 6, 7, 7, 8, 9}
O C. {1, 2, 3, 4, 6, 7, 8, 9}
OD. {2, 6, 7}

the answer would be {2,7,6}

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)
