Question

The line 1, with equation y + 2x - 4 = 0 passes through the point with coordinates
(a, 6) and she point with coordinates (3.b).
(a) Find the value of d'and, the value of b.
The line 1, passes through point P and is perpendicular to 1,
The point R, with coordinates (e, lies on 1, such that PR = 6×5^1/2
(b) Find the two possible pairs of values of e and f.
Given that e < 0.
find the area of triangle POR
The points P. and R lie a circle C
(d) Find the coordinates of the centre of C​

Answer 1

Answer:

As line passes through (1,4) & (2,5)

⇒4=m+c...(1) [(2)-(1)]

& 5=2m+c...(2)

⇒

c=3,m=1
