Answer:
Therefore the coordinates of C is
C(4,9).
Step-by-step explanation:
Given:
Point A , B , and C are Collinear.
i.e A-B-C is a Straight Line
AB : BC = 1 : 1
i.e B is the Mid Point of AC.
And Point A , B and C lie on the Same Line
point A( x₁ , y₁) ≡ ( 0 ,-9)
point B( x , y) ≡ (2 , 0)
To Find:
point C( x₂ , y₂) ≡ ?
Solution:
B is the Mid Point of AC. Hence by Mid point Formula,
Substituting the values we get
Substituting x and y value we get
Therefore the coordinates of C is
C(4,9).
5(12x)=8x+26
60x=8x+26
52x=26
x=2
The dimensions of the scale drawing would be 56 units by 16 units.
