Write the equation 3x + y = -10 in the point-slope form * y - 10 = 3(x - 0)
y + 10 = 1(x - 0)
y + 10 = 3(x - 0)
y - 0 = -3(x + 10)

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
