What is the graph of the equation (x+8)^2+(y-1)2=9
2 answers:
Answer:
option (b) is correct.
Step-by-step explanation:
Given : the equation
We have to plot the graph for the given equation and choose the correct graph
Since the general equation of circle is given as,
Where (h, k) is the center of the equation and r is the radius.
Thus, for the given equation
on comparing we have h = -8 , k = 1 , r = 3
Thus, the graph will be a circle with center at (-8, 1) and radius 3 .
Thus, the graph in option (b) is correct.

Answer: The answers are 13. (A) and 14. (B).
Step-by-step explanation: The calculations are as follows:
(13) The given equations are
In the attached figure (a), these two lines are drawn. We can see that The lines intersect at the point P(8, -9). So, the solution to the pair of equations is (8, -9).
Thus, the correct option is (A).
(14) The given equations are
In the attached figure (b), these two lines are drawn. We can see that The lines intersect at the point Q(7, -2). So, the solution to the pair of equations is (7, -2).
Thus, the correct option is (B).
