Determine the x-intercept and the y-intercept of each problem.

20x + 8y = 240

15x + 3y = 270

y = 8x + 168

20x + 8y = 240

x-intercept, y = 0;

20x + 8 (0) = 240

20x = 240

x = 240/20

x = 12

y-intercept, x = 0;

20 (0) + 8y = 240

8y = 240

y = 240/8

y = 30

...

15x + 3y = 270

x-intercept, y = 0;

15x + 3 (0) = 270

15x = 270

x = 270/15

x = 18

y-intercept, x = 0;

15 (0) + 3y = 270

3y = 270

y = 270/3

y = 90

...

y = 8x + 168

x-intercept, y = 0;

0 = 8x + 168

8x = - 168

x = - 168/8

x = - 21

y-intercept, x = 0;

y = 8 (0) + 168

y = 168
