Step-by-step explanation:
The general equation of a circle with center (a, b) and radius r is given by the equation;
The constant in the right hand side of the equation is simply the square of the radius;
We have been given the following equation;
(x-3)^2 + (y+1)^2 = 16
Comparing this with the general equation above;
Answer:
The intersection point of diagonals is (0.5,-4.5).
Step-by-step explanation:
The end points of first diagonal are p(-3, -2) and i(4, -7).
The end points of second diagonal are a(4, -2) and d(-3, -7).
If a line passing through two points, then the equation of line is
The equation of first diagonal is
.... (1)
The equation of second diagonal is
.... (2)
Add equation (1) and (2),
Put this value in (1).
The intersection point of diagonals is (0.5,-4.5).
