Question

What is the slope of the line passing through the points (-3, 4) and (2, – 1)? A = - 1B = -5/3C = 1D = 3/5

Answer 1

To find the slope of a line passing through the points (-3, 4) and (2, -1), we have to follow the next steps:

1. Use the following equation:

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

2. Label each of the given coordinates:

(-3, 4) ---> x1 = -3, y1 = 4.

(2, -1) ---> x2 = 2, y2 = -1.

3. Put these values in the previous equation:

$m=\frac{-1-4}{2-(-3)}\Rightarrow m=\frac{-5}{2+3}=\frac{-5}{5}\Rightarrow m=-1$

Then, the slope is m = - 1 ( Option A).
