y-intercept:

Plug in 0 for 'x' to find the y-intercept:

7x - 3y = 21

7(0) - 3y = 21

0 - 3y = 21

-3y = 21

Divide -3 to both sides:

y = -7

So the y-intercept is -7.

x-intercept:

7x - 3y = 21

Plug in 0 for 'y' to find the x-intercept.

7x - 3(0) = 21

7x - 0 = 21

7x = 21

Divide 7 to both sides:

x = 3

So the x-intercept is 3.
