A graph of a linear equation passes through (-2,0) and (0,-6). 1. Use the two points to sketch the graph of the equation.
2. Is 3x - y = -6 an equation for this graph? Explain how you know.

Find the required measurements of the following trapezoids. a = 8 cm b = 16 cm h = 10 cm

Solve the triangle. a = 21°, c = 105°, c = 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
