If the coordinates of point A are (8,0) and the coordinates of point B are (3,7) the y-intercept of AB is ___. If the coordinates of point D are (5,5) the equation of line CD is y= x+

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
