Transcript text: Question 17, 3.4.37
Graph the linear equation using the slope and $y$-intercept.
\[
y=-\frac{7}{3} x
\]
Use the graphing tool to graph the equation. Plot the $y$-intercept and then plot second point using the rise over run of the slope, starting at the $y$-intercept.
Solution
Solution Steps
Step 1: Identify the y-intercept
The given linear equation is \( y = -\frac{7}{3}x \). This equation is in the slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. Here, \( b = 0 \), so the y-intercept is at the point (0, 0).
Step 2: Identify the slope
The slope \( m \) of the equation is \( -\frac{7}{3} \). This means for every 3 units you move to the right (positive direction on the x-axis), you move 7 units down (negative direction on the y-axis).
Step 3: Plot the y-intercept and use the slope to find another point
Plot the y-intercept (0, 0) on the graph.
From the y-intercept, move 3 units to the right (positive x-direction) and 7 units down (negative y-direction) to find the second point. This point is (3, -7).
Final Answer
To graph the equation \( y = -\frac{7}{3}x \):
Plot the y-intercept at (0, 0).
From (0, 0), move 3 units to the right and 7 units down to plot the second point at (3, -7).
Draw a straight line through these two points to represent the equation.
