a system of linear equations is graphed.

which ordered pair is the best estimate for the solution to the system?

a. (2, −6.5)

b. (0, −6.5)

c. (−1.5, 0)

d. (2.5, −6.5)

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
