#x = 25/3 = 8 1/3 " and "y = 25/(-9) = -2 7/9#

To find the x-intercept, make y = 0.
#3x -9(0) = 25#

#x = 25/3 = 8 1/3#

To find the y-intercept, make x = 0.

#3(0) -9y = 25#

#y = 25/(-9) = -2 7/9#

For the y intercept you can also change the equation into standard form , #y = mx + c#

#3x -9y = 25#

#3x- 25 = 9y#

#y = 1/3x -25/9 " " c = -25/9 #
