प्रश्न
A line segment joining P(2, –3) and Q(0, –1) is cut by the x-axis at the point R. A line AB cuts the y-axis at T(0, 6) and is perpendicular to PQ at S.
Find the:
- equation of line PQ
- equation of line AB
- coordinates of points R and S.
उत्तर
a. Slope of PQ = –1
Equation of PQ: x + y + 1 = 0
b. Slope of AB = 1
∴ Equation of line AB, x – y + 6 = 0
c. R(–1, 0)
`S(-7/2, 5/2)`
