Intercepts are: x = -3/7 and y = 3x=37andy=3

Explanation:

As long as an equation of a straight line is in the form y = mx +cy=mx+c, the y-intercept is obtained immediately from 'c'.

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

If x=0:" " y = 7(0) +3 " "rArr y = 3x=0: y=7(0)+3 y=3

If y =0:" " 0 = 7x+3y=0: 0=7x+3
" "7x = -3 " "rArr x = -3/7 7x=3 x=37
