Math Problem Statement

Graph the line described by y + 2 = (1/6)(x + 3).

Solution

The equation in the image is y+2=16(x+3)y + 2 = \frac{1}{6}(x + 3).

To graph this, let's first rewrite it in slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

  1. Start with the given equation: y+2=16(x+3)y + 2 = \frac{1}{6}(x + 3)
  2. Subtract 2 from both sides to isolate yy: y=16(x+3)2y = \frac{1}{6}(x + 3) - 2
  3. Distribute 16\frac{1}{6} on the right side: y=16x+362y = \frac{1}{6}x + \frac{3}{6} - 2
  4. Simplify the constants: y=16x+122y = \frac{1}{6}x + \frac{1}{2} - 2 y=16x32y = \frac{1}{6}x - \frac{3}{2}

Now we can see that the slope mm is 16\frac{1}{6} and the y-intercept bb is 32-\frac{3}{2}.

Graphing Instructions:

  1. Plot the y-intercept: Start by marking the point (0,32)(0, -\frac{3}{2}) on the graph, which is at (0,1.5)(0, -1.5).
  2. Use the slope: From the point (0,1.5)(0, -1.5), move up 1 unit and to the right 6 units to find another point on the line. This corresponds to a rise of 1 and a run of 6, as the slope is 16\frac{1}{6}.
  3. Draw the line: After plotting a couple of points, draw a straight line through them.

Tip: When graphing lines, always plot the y-intercept first, then use the slope to find additional points. This makes graphing quicker and more accurate.
