Math Problem Statement

Graph 3x-2y-6=0

Solution

To graph the equation 3x2y6=03x - 2y - 6 = 0, let's rewrite it in slope-intercept form (i.e., y=mx+by = mx + b), where mm is the slope and bb is the y-intercept.

Steps:

  1. Start with the equation: 3x2y6=03x - 2y - 6 = 0

  2. Solve for yy: 2y=3x+6-2y = -3x + 6 y=32x3y = \frac{3}{2}x - 3

Now, the equation is in the form y=32x3y = \frac{3}{2}x - 3. The slope is 32\frac{3}{2} and the y-intercept is 3-3.

Plotting the Graph:

  • Y-intercept: The graph crosses the y-axis at (0,3)(0, -3).
  • Slope: The slope 32\frac{3}{2} means that for every 2 units you move horizontally (to the right), you move 3 units vertically (upwards).

You can plot the point (0,3)(0, -3), and then use the slope to find another point. Starting from (0,3)(0, -3), go 2 units to the right and 3 units up to reach the point (2,0)(2, 0).

Now, draw a straight line through the points (0,3)(0, -3) and (2,0)(2, 0). That will be the graph of the equation.

Would you like me to generate the visual graph for you?
