Two lines, M and N, are represented by the following equations: Line M: y = x + 3 Line N: y = −2x + 6 Which of the following options shows the solution to the system of equations and explains why? A (1, 4), because the point does not lie on any axis
B (1, 4), because one of the lines passes through this point
C (1, 4), because both lines pass through this point
D (1, 4), because the point lies between the two axes

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
