- We have to multiply the given expression.
- Square the first term xy. Square the last term 9 .

Answer:
1. r is point
2.PQ is ray
3. pr is line
4. p.q,r is collnear points
5. QR is segment
Well, in slope-intercept form, the equation will be y = x + 4. In standard form, the equation will be x - y = -4.
