2x+-+3y+=+-18
the x-intercept is:
2x+-+3y+=+-18.....set y=o
2x+-+3%2A0+=+-18..solve for x
2x+=+-18
x+=+-18%2F2
x+=+-9...so, the x-intercept is at (-9,0)

and
2x+-+3y+=+-18.....set x=o
2%2A0+-+3y+=+-18..solve for y
-3y+=+-18...both sides multiply by -1
3y+=+18
y=+18%2F3
y=+6...so, the y-intercept is at (0,6)


graph it:
2x+-+3y+=+-18...first write it in slope-intercept form
2x+%2B18+=+3y
%282%2F3%29x+%2B6+=+y
