Answer:
A
Step-by-step explanation:
To find the slope of a line, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
So, we will need to choose two points from the graph. Any two points will work.
Let’s choose (0, -1) and (1, 2).
So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:
[tex]\displaystyle m=\frac{2-(-1)}{1-0}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{3}{1}=3[/tex]
Therefore, the slope of the line is 3.
Hence, our answer is A.
