What is the slope in the line formed by points (-1,-2) and (3,-3

tia_tia [17]

Slope of the line formed by points (-1,-2) and (3,-3) is $Slope=\frac{-1}{4}$

Step-by-step explanation:

We need to find slope of the line formed by points (-1,-2) and (3,-3)

Finding slope:

The formula used is:

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

here, $x_1=-1,y_1=-2,x_2=3,y_2=-3$

Putting values and finding slope:

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

$Slope=\frac{-3-(-2)}{3-(-1)}$

$Slope=\frac{-3+2}{3+1}$

$Slope=\frac{-1}{4}$

So, slope of the line formed by points (-1,-2) and (3,-3) is $Slope=\frac{-1}{4}$
