Answer to Problem 23AYU
Explanation of Solution
Given:
Equation of the circle
Calculation:-
Let us write the equation of the circle in standard form .
Compare this equation with the equation .
The comparison yields the information about the circle. We see that and .
The circle has centre and a radius 2 units. To graph the circle, first plot the centre . Since the radius is 2 units, locate four points on the circle by plotting 2 units to the left, to the right, up and down from the centre. These four points can be used to sketch the graph.
To find the , if any, let and solve for .
are 5 and 1.
To find the , if any, let and solve for .
Subtract 9 from both sides
This shows has no real value. Hence there is no .
