The angle between the line joining the points `(1,-2) , (3,2)` and the line `x+2y -7 =0` is

Explanation

To find the angle between the line joining the points (1, -2) and (3, 2) and the line given by the equation \(x + 2y - 7 = 0\), we can follow these steps:

### Step 1: Find the slope of the line joining the points (1, -2) and (3, 2).

The formula for the slope \(m\) of a line joining two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by:

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