Answer:
See below
Explanation:
WZ is horizontal:
When points W and Z are plotted on the graph and are connected to each other, it will be observed that a horizontal line is formed. Both points W and Z have a common y- coordinate. Therefore the horizontal line will pass through the y-axis at y value of 2. Horizontal lines have zero slopes.
Also the equation of line WZ is: y = 2
DG is neither
When points D and G are plotted on the graph and are connected to each other, it will be observed that neither a horizontal or vertical line is formed. Instead an oblique (or slanted) line is found. This oblique line will have a negative slope and will pass through the y-axis at y value of
Also the equation of line DG is:
