Answer

To graph the line \( y = \frac{3}{5}x + 4 \), plot the \( y \)-intercept at \( (0, 4) \) and use the slope \( \frac{3}{5} \) to find another point, such as \( (5, 7) \). Draw a straight line through these points.

Solution

Function by following steps: - step0: Find the y-intercept: \(y=\frac{3}{5}x+4\) - step1: Set \(x\)=0\(:\) \(y=\frac{3}{5}\times 0+4\) - step2: Multiply: \(y=0+4\) - step3: Remove 0: \(y=4\) Analyze the slope of the function \( y=\frac{3}{5}x+4 \) Function by following steps: - step0: Find the slope: \(y=\frac{3}{5}x+4\) - step1: Identify the slope: \(m=\frac{3}{5}\) To graph the line given by the equation \[ y = \frac{3}{5} x + 4 \] we can identify the slope and the \( y \)-intercept: 1. **Slope (\( m \))**: The slope of the line is \( \frac{3}{5} \). This means that for every 5 units you move to the right (in the positive \( x \) direction), the line rises 3 units (in the positive \( y \) direction). 2. **\( y \)-intercept**: The \( y \)-intercept is 4, which means the line crosses the \( y \)-axis at the point \( (0, 4) \). ### Steps to Graph the Line: 1. **Plot the \( y \)-intercept**: Start by plotting the point \( (0, 4) \) on the graph. 2. **Use the slope to find another point**: From the point \( (0, 4) \), use the slope \( \frac{3}{5} \): - Move 5 units to the right (to \( x = 5 \)). - Move 3 units up (to \( y = 7 \)). - This gives you the point \( (5, 7) \). 3. **Draw the line**: Connect the points \( (0, 4) \) and \( (5, 7) \) with a straight line, extending it in both directions. ### Points to Select on the Graph: - \( (0, 4) \) (the \( y \)-intercept) - \( (5, 7) \) (using the slope) You can also find additional points by continuing to apply the slope or by substituting other \( x \) values into the equation.

Bonus Knowledge

To graph the line represented by the equation \( y = \frac{3}{5} x + 4 \), start by identifying the slope and \( y \)-intercept. The \( y \)-intercept is 4, meaning the line crosses the \( y \)-axis at the point (0, 4). From this point, use the slope \( \frac{3}{5} \) to find another point on the line: move up 3 units (rise) and 5 units to the right (run) to reach (5, 7). Plot both points and draw a line extending through them for the complete representation of the equation. Don’t forget to label the axes and perhaps even add arrows at both ends of the line to denote that it continues infinitely!
