Question 611626:  Classify the conic section and write its equation in standard form 
x^2 +4^2-6x-16y+21=0
 
Solve the system 
4x^2+y^2=16 
x+y=2
 
Graph the equation 
(x-2)^2+(y+1)^2=9

You can  put this solution on YOUR website! (1) parabola,x^2-6x-16y+37=0
 
(2) y=2-x
 
(3)circle,,,,to graph just draw a straight line going down,(y) at the top.draw a straight line going accross with (x) on the left side of the line,on your left side bottom you write -2, on the right side you write 2,4,6, your graph should be made a circle with most of the circle touching near the 4,and the rest should be near each 2 that you have on your graph
