Math Problem Statement
Solution
The equation given is , which is in slope-intercept form, , where:
- is the slope.
- is the y-intercept.
To graph this line:
-
Start with the y-intercept: The point where the line crosses the y-axis is at . So, plot the point on the graph.
-
Use the slope: The slope means "rise over run," which translates to:
- From the y-intercept , move 3 units up (positive rise) and 2 units to the right (positive run) to get the next point, which is at . Plot the point .
-
Plot more points if needed: For accuracy, repeat this process starting from the y-intercept and moving along the slope:
- You could also move in the opposite direction (3 units down and 2 units left) to plot the point .
-
Draw the line: Connect these points with a straight line to complete the graph of the equation.
Would you like me to create a visual graph for you based on these points? Let me know if you need more details.
Here are some related questions for practice:
- What happens to the graph if the slope changes to ?
- How would you graph ?
- What is the x-intercept of the line ?
- How does changing the y-intercept affect the position of the line?
- How would the line change if the slope were zero?
Tip: The slope defines the angle of inclination of the line, while the y-intercept fixes where it crosses the y-axis.
