Question 688436
Solve for y
{{{x/9 - y/2 = 1}}} ==> multiply the entire equation by 18 (LCM of 9 and 2)
2x - 9y = 18
9y = 2x - 18 ==> divide the entire equation by 9
y = {{{(2/9)x-2}}}
...
The y intercept is -2
plot (0, -2)
...
The x intercept is where y = 0, so 
0 = {{{(2/9)x-2}}}
2 = {{{(2/9)x}}}
{{{2(9/2) = x}}}
x = 9
plot (9, 0)
...
Draw a line through the intercepts
