The #y# intercept: #y=25/7#
The #x# intercept: #x=25/3#

Explanation:

We have
#3x+7y=25#
For x=0# we get #y=25/7# For #y=0# we get #x=25/3#

x intercept is #x=25/3# and y intercept is #y=25/7#

Explanation:

#3 x +7 y =25 # , x intercept is obtained by putting #y=0#

in the equation. #:. 3 x +7*0 =25 or 3 x= 25 :. x= 25/3 #

Therefore, x intercept is #x=25/3#. Similarly y intercept is obtained

by putting #x=0# in the equation. #:.3*0 +7 y =25 # or

# 7 y= 25 :. y= 25/7 #. Therefore, y intercept is #y=25/7#
