Math Problem Statement

Graph the following features: Slope = -2, Y-intercept = 1.

Solution

To graph the equation using the given features:

  • Slope = -2
  • Y-intercept = 1

The equation of the line can be written in slope-intercept form:
y=mx+by = mx + b
where mm is the slope and bb is the y-intercept. Substituting the values:
y=2x+1y = -2x + 1

Steps to Graph:

  1. Plot the Y-Intercept: The y-intercept is 11, so mark the point (0,1)(0, 1) on the graph.
  2. Use the Slope: The slope 2-2 means "rise over run" is 21\frac{-2}{1}.
    • From (0,1)(0, 1), move down 2 units and right 1 unit to get the next point, (1,1)(1, -1).
    • Repeat this step to plot additional points if needed.
  3. Draw the Line: Use a ruler to draw a straight line through the points.

Would you like me to generate a digital representation of this graph or explain anything further?

Related Questions:

  1. How can you rewrite the slope-intercept equation into standard form?
  2. What does the slope of 2-2 tell you about the direction of the line?
  3. How would the graph change if the slope were positive instead?
  4. What is the significance of the y-intercept in real-world scenarios?
  5. How can you verify the accuracy of your graph mathematically?

Tip:

To check your graph, substitute the x-values of your plotted points into the equation y=2x+1y = -2x + 1. If the equation holds true, your points are correct!
