        graphing
       
                  
        I can't draw graphs but I can tell you how to graph these relations.
 In question b)  solve for x and the graph is a straight  vertical line.
 
 In question  d) solve for why and the graph is a straight horizontal line.
 
 The graphs of a) and c) are straight lines.
 
 To plot them first let x=0 and solve for why.
 That gives the point of intersection of the line with
 The why axis. Then let y=0 and solve for x. That gives the point of intersection of the line with the x axis.
 Plot these points of intersection and draw a line
 Through them.
 
 E)
 
 4x^2 + 24x+4y^2 -32y+20=0
 
 Divide both sides by 4
 
 X^2 + 6x + y^2 -8y +5 = 0
 
 Complete the square in terms in x and y
 
 X^2+6x+9+y^2-8y+16 +5-9-16=0
 
 (x+3)^2 + (y-4)^2 -20=0
 
 (x+3)^2 + (y-4)^2 = 20
 
 This is a circle with center at point (-3,4)
 And radius 2sqrt 5
