Question 501304
To find the x intercepts set y=0 and solve for x
To find the y intercepts set x=0 and solve for y

For eqn 1   x - y - 3= 0

x-0-3=0     add 3 to both sides
x=3

0-y-3=0    add y to both sides
y=-3

For eqn 2    -7x - 14y - 5= 0

-7x-0-5=0    add 5 to both sides
-7x=5        divide both sides by -7
x=-5/7

-0-14y-5=0   add 5 to both sides
-14y=5       divide both sides by -14
y=-5/14

For eqn 3    6x + 4y= -5

6x+0=-5      divide both sides by 6
x=-5/6

0+4y=-5      divide both sides by 4
y=-5/4
