Question

Find the equation of the line with slope 0 and passing through (-5,16). Write the equation in standard form.

Answer 1

Lines with a slope of zero can be thought of as y = 0x + b, which simplifies to just "y = b".

In this case, your equation is y = 16.

If you want to force it explicitly into standard form, you could write it at
0x + 1y = 16
