Math Problem Statement

Graph the line given by the equation y + 5 = (1/2)(x + 6).

Solution

Let's solve and graph the given equation:

The line provided is:
y+5=12(x+6)y + 5 = \frac{1}{2}(x + 6)


Step 1: Rewrite into slope-intercept form y=mx+by = mx + b.

  1. Start with the equation:
    y+5=12(x+6)y + 5 = \frac{1}{2}(x + 6)
  2. Distribute the 12\frac{1}{2} on the right side:
    y+5=12x+3y + 5 = \frac{1}{2}x + 3
  3. Subtract 55 from both sides:
    y=12x+35y = \frac{1}{2}x + 3 - 5
  4. Simplify:
    y=12x2y = \frac{1}{2}x - 2

The equation of the line is now in slope-intercept form y=mx+by = mx + b, where:

  • Slope (mm) = 12\frac{1}{2}
  • Y-intercept (bb) = 2-2

Step 2: Plot the line.

  1. Start at the y-intercept b=2b = -2. Plot the point (0,2)(0, -2).
  2. Use the slope 12\frac{1}{2} (rise over run):
    • From (0,2)(0, -2), go up 1 unit and right 2 units to reach the next point (2,1)(2, -1).
    • Continue this to find additional points if necessary.
  3. Draw a straight line through the points.

Key Points for Graphing:

  • The line passes through:
    • (0,2)(0, -2) (y-intercept)
    • (2,1)(2, -1) (using the slope).
  • The slope indicates the line rises 1 unit for every 2 units to the right.
