Math Problem Statement

Graph the line y = (3/2)x + 3

Solution

The equation given is y=32x+3y = \frac{3}{2}x + 3, which is in slope-intercept form, y=mx+by = mx + b, where:

  • m=32m = \frac{3}{2} is the slope.
  • b=3b = 3 is the y-intercept.

To graph this line:

  1. Start with the y-intercept: The point where the line crosses the y-axis is at (0,3)(0, 3). So, plot the point (0,3)(0, 3) on the graph.

  2. Use the slope: The slope 32\frac{3}{2} means "rise over run," which translates to:

    • From the y-intercept (0,3)(0, 3), move 3 units up (positive rise) and 2 units to the right (positive run) to get the next point, which is at (2,6)(2, 6). Plot the point (2,6)(2, 6).
  3. 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 (2,0)(-2, 0).
  4. 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:

  1. What happens to the graph if the slope changes to 52\frac{5}{2}?
  2. How would you graph y=32x+3y = -\frac{3}{2}x + 3?
  3. What is the x-intercept of the line y=32x+3y = \frac{3}{2}x + 3?
  4. How does changing the y-intercept affect the position of the line?
  5. 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.
