Match the ordered pairs so that the relation defined by the set of ordered pairs does not represent a function. tiles: (2, 3) (-5, 2) (-5, 1) (6, -5) (6, 5) (2, 2) (0, 3) (-1, 0) (-1, 6)

Here are the matches:

(-5,2) and (-5,1)

(2,3) and (2,2)

(6, 5) and (6, -5)

(-1, 6) and (-1, 0)

I got these right on the test, so they are right.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

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)
