What is the slope of the line show belowww

zaharov [31]

Answer:

$\boxed{C.\:\: 2}$

Step-by-step explanation:

The given line passes through the points,

$(x_1,y_1)=(-2,-3)$ and $(x_2,y_2)=(3,7)$ .

We can find the slope using the following;

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

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

Using the first formula;

We obtain;

$m=\frac{7--3}{3--2}$

$\Rightarrow m=\frac{7+3}{3+2}$

$\Rightarrow m=\frac{10}{5}$

$\Rightarrow m=2$

The correct answer is C.
