Answer 2

Answer:

Step-by-step explanation:

a - b = 1

=> a = b + 1

Points:

A(-2,1)

B(a,b) = (b+1,b)

C(4,-1)

1/2 x [a1(b2-b3) + a2(b3-b1) + a3(b1-b2)] = 0

1/2 x [(-2)(b-(-1)) + (b+1)(-1-1) + 4(1-b)] = 0

1/2 x [(-2)(b+1)) + (b+1)(-2) + 4(1-b)] = 0

1/2 x (-2b-2-2b-2+4-4b) = 0

1/2 x (-8b) = 0

-8b/2 = 0

-4b = 0

b = 0

a = b + 1

a = 0 + 1

a = 1

Coordinates of point-B = (1,0)
