Which of the sets of ordered pairs represents a function? a = {(3, –5), (4, 6), (–3, 9), (2, 7)} b= {(2, 4), (–1, –7), (5, 6), (4, 3)} (5 points) only a only b both a and b neither a nor b

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
