The equations of two lines are shown below. 3x-2y= -5 2x+3y=5 which statement about the graphs of the two lines is correct? a. the lines are parallel because the constants are opposites. b. the lines are perpendicular because the constants are opposites. c. the lines are perpendicular because the slopes are opposite reciprocals of one another. d. the lines are parallel because the slopes are opposite reciprocals of one another.

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
