Suppose y=x-1. Describe the graph of y=3(x-1).

Explanation

To describe the graph of \( y = 3(x - 1) \) in relation to the graph of \( y = x - 1 \), we will follow these steps:

### Step 1: Understand the original function
The original function is \( y = x - 1 \). This is a linear function with a slope of 1 and a y-intercept of -1.

### Step 2: Find key points of the original function
To graph \( y = x - 1 \), we can find some key points:
- When \( x = 0 \):
