Answer:
a) y=7 is a horizontal line then its slope is 0.
b) It is a slanted line, its slope is 2/3.
c) x=5 is a vertical line, so its slope is undefined.
Step-by-step explanation:
A line is represented by the following expression:
[tex]\begin{gathered} y=mx+b \\ \text{where,} \\ m=\text{slope} \end{gathered}[/tex]The slope is defined by a change in y/change in x. The slope of a horizontal line is 0. The slope of a vertical line is undefined.
Therefore,
a) y=7 is a horizontal line then its slope is 0.
b) It is a slanted line, its slope is 2/3.
c) x=5 is a vertical line, so its slope is undefined.
