x intercept is 7/4 and y intercept is 7/3.

Explanation:

For y=0,
color(white)(xx)4x-7=0
=>4x-7color(red)(+7)=0color(red)(+7)
=>color(red)(1/4xx)4x=color(red)(1/4xx)7
=>x=7/4

Therefore x intercept is 7/4.

For x=0,
color(white)(xx)3y-7=0
=>3y-7color(red)(+7)=0color(red)(+7)
=>color(red)(1/3xx)3y=color(red)(1/3xx)7
=>x=7/3

Therefore y intercept is 7/3.
