The slope is $1$ .

To find the slope given two points, we use the formula $"rise"/"run"$ , or $(y_2-y_1)/(x_2-x_1)$ .

Plug in the given points into the formula:
$(5-2)/(2-(-1)) = 3/3 = 1$

Therefore, the slope is $1$ .

$1$

To find the slope for two points, we can use the formula

$(Deltay)/(Deltax)$

Where the Greek letter Delta ( $Delta$ ) is shorthand for "change in".

We just see how much our $y$ changes, and divide by how much our $x$ changes.

We go from $y=2$ to $y=5$ , which represents a $Deltay$ of $3$ .

We go from $x=-1$ to $x=2$ , which represents a $Deltax$ of $3$ .

Therefore, our slope is $1$ .

Hope this helps!
