Both A & B
1. (x1,y1) or (x, y)
2. point-slope or slope-intercept
3. y or x
4. slope-intercept or point slope

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
