Which equation represents a line with slope 2/3 and y-intercept –6?

a. 2x + 3y = −6
b. 3x − 2y = 6
c. 3x − 2y = 12
d. 2x − 3y = 18

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
