Answer:
The answer to your question is below
Step-by-step explanation:
Process
1.- Find to points of each line
2.- Substitute the values of the points in the formula
([tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
3.- Simplify to find the slope
Line A
([tex]m = \frac{3 - 1}{2 - 1}[/tex]
[tex]m = \frac{2}{1}[/tex]
m = 1
Line B
([tex]m = \frac{3 - 3}{2 - 1}[/tex]
[tex]m = \frac{0}{1}[/tex]
m = 0
Line C
([tex]m = \frac{2 - 0}{-2 - 4}[/tex]
[tex]m = \frac{2}{-6}[/tex]
[tex]m = - \frac{1}{3}[/tex]
Line D
([tex]m = \frac{3 - 1}{-1 - 2}[/tex]
[tex]m = \frac{2}{-3}[/tex]
