Math Problem Statement

A line has a slope of 1/2 and a y-intercept of 6. Graph this line.

Solution

To graph the line with a slope of 12\frac{1}{2} and a yy-intercept of 6, we can use the slope-intercept form of a linear equation:

Slope-Intercept Form:

y=mx+by = mx + b where:

  • mm is the slope of the line,
  • bb is the yy-intercept.

Given values:

  • Slope m=12m = \frac{1}{2},
  • yy-intercept b=6b = 6.

Equation of the Line:

Substitute mm and bb into the formula: y=12x+6y = \frac{1}{2}x + 6

Steps to Graph the Line:

  1. Plot the yy-intercept (0,6): Start by plotting the point where the line crosses the yy-axis at (0,6)(0, 6).

  2. Use the Slope to Find Another Point: The slope 12\frac{1}{2} means that for every 1 unit increase in xx, yy increases by 12\frac{1}{2}. Starting from (0,6)(0,6):

    • Move 1 unit to the right (in the xx-direction) and 0.5 units up (in the yy-direction) to get the next point at (1,6.5)(1, 6.5).
  3. Draw the Line: Connect these points with a straight line, extending it in both directions.

Would you like me to provide a visual graph of this line?


Here are some follow-up questions for further practice:

  1. What would be the equation of a line with the same slope but a yy-intercept of 3?
  2. How would the graph change if the slope were negative, say 12-\frac{1}{2}?
  3. What is the equation of a line that passes through the origin with a slope of 12\frac{1}{2}?
  4. How can you determine the slope and yy-intercept from any linear equation?
  5. How would you graph a line given two points instead of the slope and yy-intercept?

Tip: Remember that the slope describes the "rise over run," helping you move from point to point on the graph.
