QUESTION 1
The point C(3.6, -0.4) divides AB in the ratio 3 : 2.
The coordinates of A are (-6, 5).
Let the coordinates of B be
We use the formula:
to determine the x-coordinate of B.
We substitute the known values to obtain:
This implies that:
We also use the formula:
to find the y-coordinate.
The coordinates of B are (10,-4)
QUESTION 2.
If point D divides CD in the ratio 4 : 5.
Then the coordinates of D are:
The coordinates of D are
The answer is x = 62. YOU'RE WELCOME :D
Points are graphed on a coordinate plane by placing a dot on a location on a graph.
Multiply first formula by 2, then do formula 1-formula 2
