Which set of ordered pairs is a function? 0 (-3,-1),(-3,0),(-3, 3),(-3,5)
0 (-2,-1),(-1,0),(0,0), (2,1)
0 (-1,-1),(-1,0),(0,0),(0,1)
O (0,0),(3,0), (3, 3), (4,0)

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
