Determine whether the given ordered pair is a solution of the given equation.
x^2 + y^2 - 8x + 6y = -21; (4,-1)
a. no
b. yes
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
The first number in your ordered pair is the 
-coordinate of the point and the second number is the 
-coordinate. Substitute the value of the -coordinate for in your equation and Substitute the value of the -coordinate for :
^2 + (-1)^2 - 8(4) + 6(-1) =^? -21)
Do the arithmetic. If the result is a true statement, then your answer is yes, the given point is on the graph. Otherwise the answer is no.
