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=(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=(-1-4)/(2-(-3))\Rightarrow m=(-5)/(2+3)=(-5)/(5)\Rightarrow m=-1`

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