Can someone answer this

give an example of a line with undefined slope and one with zero slope.
what is the difference if you were to plot your equations.

Zero slope line coinciding with x axis and undefined slope line coinciding with y axis

Slope=rise/run
when rise=0 or when it is a horizontal line (y=something, a line that goes straight left and right) then you get a zero slopoe

when run=0, or when it goes up and down infinitely or vertical line (x=something) you get undefined slope because rise/0 is undfined

zero slope would be y=c where c is a constant
undefined slope would be x=c where c is a constant

zero slope is a horizontal line
undefined slope is a vertical line

Step-by-step explanation:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
