The point (-3,-5) is on the graph of a function. Which equation must be true regarding the function?
f(-3) = -5
f(-3,-5) = -8
f(-5) = -3
f(-5, -3) = -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
