What is the slope of a line that contains the points (1 -2) and (4, -3).
Naddika [18.5K]

Answer:

-\frac{1}{3}

Step-by-step explanation:

Use the definition of slope:

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

Replace the values in the equation and solve:

m=\frac{-3-(-2)}{4-1} \\m=\frac{-1}{3}\\m=-\frac{1}{3}
