Answer:
Step-by-step explanation:
A horizontal line has no slope, y=0x+b, whereas a vertical line has an undefined slope x=[a constant which is the x intercept, there is no y intercept]. So, yes.
The slope of a horizontal line is undefined is true.
What is slope of a straight line ?
The Slope (also called Gradient) of a straight line shows how steep a straight line is. It is also used for measuring the inclination of a straight line with respect to a definite axis.
Why slope of a straight line is not defined ?
A straight line is represented as y = mx + c where m is the slope of the straight line and c is the y-intercept of the straight line.
A line can have undefined slope when the value of m is 0 .
Then we have the equation as - y = (0)x + c ⇒ y = c.
Therefore the given statement is true.
