What is the equation, in standard form, of a parabola that contains the following points?
(-2, -11.5), (0, -2., -20.5)

y = -1.5x2 + 1.5x - 2.5
y = 1.5x2 - 1.5x - 2.5
y = 2.5x2 + 1.5x + 1.5
y = 1.5x2 - 1.5x + 2.5

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
