The equation is a straight line with a slope of and a y-intercept at (0, -4). It crosses the x-axis at (12, 0).

Solución

Certainly! Let’s analyze the linear equation you’ve provided:
This equation is in slope-intercept form, which is generally written as:
where:
  • is the slope of the line.
  • is the y-intercept, the point where the line crosses the y-axis.

Breakdown of the Equation

  1. Slope ( ):
    • In your equation, .
    • Interpretation: For every increase of 3 units in , increases by 1 unit.
    • Graphically: The line rises gently from left to right.
  2. Y-Intercept ( ):
    • Here, .
    • Interpretation: The line crosses the y-axis at the point (0, -4).
    • Graphically: Start your graph at the point (0, -4).

Graphing the Equation

To graph the equation :
  1. Plot the Y-Intercept:
    • Start by plotting the y-intercept at (0, -4).
  2. Use the Slope to Find Another Point:
    • The slope means “rise over run.” So, for every 3 units you move horizontally (run) to the right, you move 1 unit vertically (rise) upwards.
    • Starting from (0, -4), move 3 units to the right to , and 1 unit up to . Plot the point (3, -3).
  3. Draw the Line:
    • Connect the two points with a straight line extending in both directions.

Additional Features

  • X-Intercept:
    • To find where the line crosses the x-axis, set and solve for :
    • So, the x-intercept is at (12, 0).
  • Increasing/Decreasing:
    • Since the slope is positive, the line is increasing; as increases, also increases.

Summary

  • Slope: (gentle upward incline)
  • Y-Intercept: (0, -4)
  • X-Intercept: (12, 0)
  • Graph: A straight line crossing the y-axis at (0, -4) and the x-axis at (12, 0), rising as it moves from left to right.

Did you know that the equation you provided, , represents a straight line on a graph? The slope of indicates that for every 3 units you move to the right along the x-axis, you’ll move up 1 unit on the y-axis. This slope is gentle, giving the line a nice, gradual incline!
Now, if you’re looking to find the x-intercept of this line, you can set to 0 and solve for . Setting leads to . This means the line crosses the x-axis at (12, 0). A great way to visualize graphing this line is to plot these points and connect them—it’ll help reinforce your understanding of linear equations!
