The y intercept is the value of y when x is equal to 0, so just set x=0 and find y!
y = 0-3
y=-3
The answer is C: (0,-3)
I hope this helped! ^-^

The y-intercept is found when the x-coordinate is equal to zero, so if you plug 0 into the x-variable of the equation, you can find the intercept.
y = x - 3 Plug in 0 for x
y = 0 - 3 Subtract
y = -3 So when x = 0, then y will equal -3. This means that the y intercept of the equation will be C. (0, -3).
