Question

What is the slope of the line? A: 3 B: - 3 C: - 1 D: 1

Answer 1

Answer:

A

Step-by-step explanation:

To find the slope of a line, we can use the slope formula:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

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:

$\displaystyle m=\frac{2-(-1)}{1-0}$

Evaluate:

$\displaystyle m=\frac{3}{1}=3$

Therefore, the slope of the line is 3.

Hence, our answer is A.
