Multiply the entire equation by 36 (the LCM of 4 and 9)
...
36%28x%2F9%29+-+36%28y%2F4%29+=+36%281%29
...
4x - 9y = 36
4x - 36 = 9y
...
y+=+%284%2F9%29x+-+36%2F9
highlight%28y=%284%2F9%29x-4%29
...
y intercept is -4
Plot (0, -4)
...
x intercept is where y = 0
0 = 4%2F9x - 4
4 = 4%2F9x
9%2F4(4) = x
x = 9
Plot (9, 0)
...
Draw a line through the intercepts
