$(deltay)/(deltax) = -1$

Slope is $"rise"/"run"$ , or the change in $y$ divided by the change in $x$ . Mathematically this is shown as

$(deltay)/(deltax)$

To find the change in a value, take the second one and subtract the first, or

$deltan = n_2 - n_1$

Therefore,

$deltay = 4 - (-1) = 5$
$deltax = -3 - 2 = -5$

Which means

$(deltay)/(deltax) = 5/-5 = -1$

which is the slope of the line.
