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:
Step 1: Rewrite into slope-intercept form .
- Start with the equation:
- Distribute the on the right side:
- Subtract from both sides:
- Simplify:
The equation of the line is now in slope-intercept form , where:
- Slope () =
- Y-intercept () =
Step 2: Plot the line.
- Start at the y-intercept . Plot the point .
- Use the slope (rise over run):
- From , go up 1 unit and right 2 units to reach the next point .
- Continue this to find additional points if necessary.
- Draw a straight line through the points.
Key Points for Graphing:
- The line passes through:
- (y-intercept)
- (using the slope).
- The slope indicates the line rises 1 unit for every 2 units to the right.
