would the y-intercept for y + x = -5 be (0,5)

y intercept is when x is zero. No, you are wrong, it is (0,-5)

The intercept would be 5 right?

To find the y-intercept of a linear equation, you need to determine the value of y when x is equal to zero. In the equation y + x = -5, we can substitute 0 for x since it is the value at the y-intercept.

So, let's solve the equation when x = 0:
y + 0 = -5
y = -5

Therefore, the y-intercept of the equation y + x = -5 is (0, -5), not (0, 5).
