identify the initial value and rate of change for the graph shown.

select one:
a. initial value: 1, rate of change: 2
b. initial value: 2, rate of change: 1 over 2.
c. initial value: 2, rate of change: 1
d. initial value: 1 over 2., rate of change: 2

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
