Question 1083266
Sketch the graph of each line.

{{{4x+5=5y}}}....here, you have an linear equation and graph is a line; so, all you need is two points

{{{x}}}|{{{y}}}
 
{{{0}}}|{{{1}}}...if {{{x=0}}}->{{{4*0+5=5y}}}->{{{5=5y}}}->{{{y=1}}}

{{{-5/4}}}|{{{0}}}...if {{{x=0}}}->{{{4x+5=5*0}}}->{{{4x+5=0}}}->{{{4x=-5}}}->{{{x=-5/4}}}

plot these points and draw a line though:

{{{drawing( 600, 600, -10, 10, -10, 10,
circle(0,1,.12),circle(-5/4,0,.12),
locate(0,1,p(0,1)),locate(-6/4,0,p(-5/4,0)),
 graph( 600, 600, -10, 10, -10, 10, 4x/5+1)) }}}
