Math Problem Statement

I need to graph the following features Y-intercept: 1 and slope=-2/3

Solution

To graph a line with the given features, y-intercept = 1 and slope = -2/3, follow these steps:

Step-by-Step Instructions:

  1. Start at the y-intercept: The y-intercept is the point where the line crosses the y-axis. For this line, the point is (0,1)(0, 1).

  2. Use the slope to find another point: The slope is 23-\frac{2}{3}. This means that for every 3 units you move to the right, the line goes down 2 units.

    • From (0,1)(0, 1), move 3 units to the right (x = 3), and then 2 units down (y = -1). This gives another point: (3,1)(3, -1).
  3. Plot these points: Plot (0,1)(0, 1) and (3,1)(3, -1) on the graph.

  4. Draw the line: Use a ruler to draw a straight line through the points.

Equation of the Line:

The slope-intercept form of a line is: y=mx+by = mx + b Where:

  • mm is the slope (2/3-2/3),
  • bb is the y-intercept (1).

Thus, the equation is: y=23x+1y = -\frac{2}{3}x + 1

Would you like a graph of this line? Let me know! 😊


Related Questions:

  1. How can the slope of a line determine its steepness and direction?
  2. What happens if the slope is positive instead of negative?
  3. How can we convert this line into standard form (Ax+By=CAx + By = C)?
  4. What are parallel and perpendicular slopes to this line?
  5. How would the graph change if the y-intercept were at y=2y = 2?

Tip:

The slope tells you how steep the line is and whether it ascends (m>0m > 0) or descends (m<0m < 0) as you move left to right.
