Answer

To graph the equation \( y=3x-1 \): 1. **Plot the y-intercept** at \((0, -1)\). 2. **Use the slope** \( m=3 \) to find another point: from \((0, -1)\), move up 3 units and right 1 unit to \((1, 2)\). 3. **Draw a straight line** through these points. 4. **Optional**: Find the x-intercept at \(\left(\frac{1}{3}, 0\right)\) by setting \( y=0 \) and solving for \( x \). This will give you the graph of the equation \( y=3x-1 \).

Beyond the Answer

To graph the equation \( y = 3x - 1 \), start by identifying the y-intercept and slope. The y-intercept is found by setting \( x = 0 \), giving us the point (0, -1). Next, the slope of 3 means that for every 1 unit you move right on the x-axis, you move 3 units up on the y-axis. From (0, -1), go right 1 unit to (1, -1), then move up 3 units to reach (1, 2). Plot these points and draw a straight line through them! To check your graph, you can choose another value of \( x \), such as \( x = 2 \). Plugging that into the equation gives \( y = 3(2) - 1 = 5 \), so the point (2, 5) should also lie on the line. Connecting these points will solidify your understanding of linear relationships!
