Here is a system of equations: 3x - y = 17
x + 4y = 10

a. Solve the system by graphing the equations (by hand or using technology).

b. Explain how you could tell, without graphing, that there is only one solution to
the system.

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
