Answer:

The #x-#intercept is #(3,0)#
The #y-#intercept is #(0,5)#

Explanation:

The #x# and #y# intercepts of of a linear equation can be found by plugging #0# in for each variable and finding the solution for the other variable.

The #x#- intercept is found where #y=0#
The #y#- intercept is found where #x=0#

Solve for each independently.

#5x - 3y = 15#

#5x - 3(0) = 15#

#5x = 15#

#(cancel(5)x)/cancel5 = 15/5#

#x=3#

The #x-#intercept is #(3,0)#

#5x - 3y = 15#

#5(0) - 3y = 15#

#3y = 15#

#(cancel(3)y)/cancel3 = 15/3#

#y=5#

The #y-#intercept is #(0,5)#
