Find the equation of a straight line: with slope -1/3 and y-intercept -4.

Explanation

To find the equation of a straight line with a given slope and y-intercept, we can follow these steps:

### Step 1: Identify the slope and y-intercept
The slope (m) is given as -1/3, and the y-intercept (c) is given as -4.

### Step 2: Write the equation of the line in slope-intercept form
The slope-intercept form of a straight line is given by the equation:
\[ y = mx + c \]
