(7,0) and (0,7)

Explanation:

Intercepts can be found by setting one variable to zero and the solving for the remaining variable.

Given:

x+y=7

We solve for the x-intercept by setting y=0.

x+0=7

=>x = 7

We solve for the y-intercept by setting x=0.

0+y=7

=>y = 7

Hence, we have intercepts at x=7, y=7.

Equivalently, the points are (7,0) and (0,7).
