Compute slope with $\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$ using the two points you chose.

As you move from left to right along the line, does $y$ increase or decrease? That tells you whether the slope is positive or negative.

In Desmos, enter the points $(-2,5)$ and $(2,-3)$.

Use an expression for slope:

Substitute $(-2,5)$ for $(x_1,y_1)$ and $(2,-3)$ for $(x_2,y_2)$.

Simplify the result to get the slope of line $m$, which matches one of the answer choices.

From the graph, line $m$ passes through points $A(-2,5)$ and $B(2,-3)$.

Compute slope using $\frac{\Delta y}{\Delta x}$:

So, the slope of line $m$ is $-2$.
