Given:
points (2,2) and (-4,2)
Recall the formula for determining the slope of a line given two points
[tex]\begin{gathered} m=\dfrac{y_2 - y_1}{x_2 - x_1} \\ \text{where} \\ (x_1,y_1)\text{ and }(x_2,y_2)\text{ are two points in the line} \end{gathered}[/tex]
Given the point (2,2) and (-4,2), the slope of the line is
[tex]\begin{gathered} (x_1,y_1)=(2,2) \\ (x_2,y_2)=(-4,2) \\ \\ m=\dfrac{y_2 - y_1}{x_2 - x_1} \\ m=\dfrac{2 - 2}{-4 - 2} \\ m=\dfrac{0}{-6} \\ m=0 \end{gathered}[/tex]
The slope of the line is zero.
Graphing the two point, connect the two points (2,2) and (-4,2), then draw a solid line connecting the two points and we get
