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
