x-y=3

The equation you've provided, \( x - y = 3 \), is a linear equation in two variables (x and y). It can be interpreted in several ways. Here are a few things you can do with it:

1. Solve for y: You can rearrange the equation to express y in terms of x: \[ y = x - 3 \]

2. Graph the equation: To graph this equation, you can identify the y-intercept and the slope.

   • When \( x = 0 \), \( y = 0 - 3 = -3 \) (the y-intercept).
   • The slope (m) of the equation is 1 (the coefficient of x), which indicates that for every increase of 1 in x, y increases by 1.

3. Find specific solutions: You can also find specific pairs of (x, y) that satisfy the equation. For example:

   • If \( x = 4 \), then \( y = 4 - 3 = 1 \). So, (4, 1) is a solution.
   • If \( x = 2 \), then \( y = 2 - 3 = -1 \). So, (2, -1) is another solution.

4. Identify intercepts:

   • x-intercept: Set \( y = 0 \): \[ x - 0 = 3 \implies x = 3 \quad \text{(Point (3, 0))} \]
   • y-intercept: Set \( x = 0 \): \[ 0 - y = 3 \implies y = -3 \quad \text{(Point (0, -3))} \]

5. Convert to slope-intercept form (which is already done in the first step): \( y = 1x - 3 \).
