Determine which of the lines are parallel and which of the lines are perpendicular. Select all of the statements that are true. Line a passes through (−3, 0) and (0, 1). Line b passes through (−2, 3) and (2, 7). Line c passes through (−1, −3) and (2, 9). Line d passes through (−2, 10) and (3, −5).

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

Find the volume of the solid bounded by the plane z=0 and the paraboloid z=1-x^2 –y^2

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
