Answer:
14) [tex]m=2[/tex]
15) [tex]m=-1[/tex]
16) [tex]m=0[/tex]
Step-by-step explanation:
In order to calculate the slope of a line, we can use this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The procedure is:
- Choose two points on line.
- Substitute the coordinates into the formula and evaluate.
Then:
14) Point (0,0) and Point (1,2):
Slope: [tex]m=\frac{2-0}{1-0}=-2[/tex]
15) Point (0,0) and Point (-2,2):
Slope: [tex]m=\frac{0-2}{0-(-2)}=-1[/tex]
16) Since it is an horizontal line, the slope is zero:
[tex]m=0[/tex]
