write an equationfor a line with zero slopeand an equationfor a line with undefined slope how do the lines differ

Answer 1

A line with zero slope is a horizontal line and the equation would be y = (some constant). An example is y = 2.

A line with an undefined slope is a vertical line and the equation would be x = (some constant). An example would be x = 7

Answer 2

zero slope is a horizontal line x = any value, e.g., x = 3

undefined slope is a vertical line y = any value, e.g., y = 3
