Question 677884
Multiply the entire equation by 36 (the LCM of 4 and 9)
...
{{{36(x/9) - 36(y/4) = 36(1)}}}
...
4x - 9y = 36
4x - 36 = 9y
...
{{{y = (4/9)x - 36/9}}}
{{{highlight(y=(4/9)x-4)}}}
...
y intercept is -4
Plot (0, -4)
...
x intercept is where y = 0 
0 = {{{4/9}}}x - 4
4 = {{{4/9}}}x
{{{9/4}}}(4) = x
x = 9
Plot (9, 0)
...
Draw a line through the intercepts
...
{{{graph(300,200,-5,15,-10,5,(4/9)x-4)}}}
