What is the equation of the line graphed?

If angle 2=3x +1 and angle 3=2x +4what is angle 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

If f(x) = 3x-2 and g(x) =2x+1 find (f-g)(x)
