Respuesta :
the answer to this question would be y= 6 since you don't have a slope you have no where to go so if you would have put and y=x+6 your saying your slope is 1 and if you say y=6x then your saying you slope is 6 and you have no y-intercept.
0 slope....means we have a horizontal line which is represented by y = a number.....so ur equation is y = 6..or y = 0x + 6
