Question

What is the slope of the line?

A: 3

B: - 3

C: - 1

D: 1

Answer 1

A

Explanation:

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

`\displaystyle m=(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=(2-(-1))/(1-0)`

Evaluate:

`\displaystyle m=(3)/(1)=3`

Therefore, the slope of the line is 3.

Hence, our answer is A.
