Mathematics: What is the amount of the tax per unit? a. $3 b. $4 c. $2 d. $1?

Step-by-step explanation:We are asked to find the slope of a line. The slope of a line gives the steepness and direction of a line. It is rise over run or the change in y over the change in x.The formula for calculating slope is: where (x₁, y₁) and (x₂, y₂) are the points the line passes through. The line passes through (0, -2) and (2, -4). If we match the values and their corresponding variable, we see that: x₁ = 0 y₁ = -2 x₂ = 2 y₂= -4 Substitute the values into the formula.

$\boxed {\boxed {\sf A. \ m= -1}}$

Step-by-step explanation:

We are asked to find the slope of a line. The slope of a line gives the steepness and direction of a line. It is "rise over run" or the change in y over the change in x.

The formula for calculating slope is:

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

where (x₁, y₁) and (x₂, y₂) are the points the line passes through. The line passes through (0, -2) and (2, -4). If we match the values and their corresponding variable, we see that:

x₁ = 0 y₁ = -2 x₂ = 2 y₂= -4

Substitute the values into the formula.

$m= \frac{(-4) - (-2)}{(2) - (0)}$
