A line segment is drawn from (3, 2) to (3, 9) on a coordinate grid.

Which answer explains one way that the length of this line segment can be determined?

A. Add 2 + 3.

B. Add 2 + 9.

C. Subtract 9 – 2.

D. Subtract 3 – 2.

How can you tell when x and y are not directly proportional?

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)

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
