- The slope of a line can be defined in words by: $\textrm{slope:=}\frac{\textrm{rise}}{\textrm{run}}$.
Rise and run refer to $\cdots$

- Let $(x_1,y_1)$ and $(x_2,y_2)$ be two points on a line. The slope of the line can be given by $\cdots$?

- Find the slope of the line which contains the points $(0,0)$ and $(-3,4)$.

- Find the slope of the line which contains the points $(-1,-1)$ and $(-2,3)$.

- Find the slope of the line which contains the points $(2,3)$ and $(5,3)$

- Find the slope of the line which contains the points $(-2,4)$ and $(-2,6)$

- The slope of any horizontal line (a line parallel to the $x$-axis) is $\cdots$?

- The slope of any line that is parallel to the $y$-axis is $\cdots$

- A line with a slope of $2$ contains the points $(1,3)$ and $(2,k)$. The value of $k$ is $\cdots$

- A line whose slope is undefined contains the points $(1,2)$ and $(h,4)$. The value of $h$ is $\cdots$?

- A line has a slope of $-3$ and contains the point $(1,-1)$. Which of the following points is on this line?

- A line has zero slope and passes through $(0,1)$. Through which of the points below does the line also pass?

- If $a$ is an integer, what is the slope of the line which contains the points $(a,a)$ and $(-a,-a)$?

- Find the slope of the line which passes through the points $(-5,-1)$ and $(2,-11)$

- A line has an undefined slope and passes through the point $(-1,1)$. The same line is likely to pass through which
of the points below?
