Math Problem Statement

graph y = -1/3 (x-6)+2

Solution

To graph the equation y=13(x6)+2y = -\frac{1}{3}(x - 6) + 2, let's break it down and identify key elements:

1. Identify the Slope and y-intercept:

  • The equation is in point-slope form, y=m(xx1)+y1y = m(x - x_1) + y_1.
  • Slope (m): 13-\frac{1}{3}. This means for every unit increase in xx, yy decreases by 13\frac{1}{3}.
  • Point (x_1, y_1): (6,2)(6, 2) is the point from which the line is drawn.

2. Plot the Point:

  • Start by plotting the point (6,2)(6, 2) on the graph.

3. Use the Slope:

  • From (6,2)(6, 2), move 1 unit to the right (increase xx by 1) and 1/3 unit down (decrease yy by 13\frac{1}{3}).
  • This gives the next point at (7,53)(7, \frac{5}{3}).

4. Draw the Line:

  • Continue plotting points using the slope, or draw a straight line through the plotted points, extending in both directions.

This graph represents a line with a negative slope, indicating it decreases as xx increases. The y-intercept can be found by setting x=0x = 0 in the equation, giving y=13(6)+2=4y = -\frac{1}{3}(-6) + 2 = 4.

Summary:

  • Slope: 13-\frac{1}{3}
  • Point: (6,2)(6, 2)
  • y-intercept: y=4y = 4
