Use this graph of y = -2x - 8x- 3 to find the vertex. Decide whether the vertex is a maximum or a minimum point.
-5
A. Vertex is a minimum point at (-2,5)
B. Vertex is a maximum point at (5,-2)
C. Vertex is a maximum point at (-2,5)
D. Vertex is a minimum point at (0, -3)

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
