Math Problem Statement

graph y = -3x + 2

Solution

To graph the equation y=3x+2y = -3x + 2, follow these steps:

1. Identify the Slope and Y-intercept

The equation is in the slope-intercept form y=mx+by = mx + b, where:

  • m=3m = -3 is the slope.
  • b=2b = 2 is the y-intercept.

2. Plot the Y-intercept

Start by plotting the y-intercept on the graph. The y-intercept is the point where the line crosses the y-axis.

  • The point is (0,2)(0, 2).

3. Use the Slope to Find Another Point

The slope 3-3 indicates that for every 1 unit you move to the right (positive direction along the x-axis), you move 3 units down (negative direction along the y-axis).

  • From (0,2)(0, 2), move 1 unit to the right to (1,2)(1, 2), then 3 units down to (1,1)(1, -1).

4. Plot the Second Point

Plot the second point (1,1)(1, -1) on the graph.

5. Draw the Line

Draw a straight line through the two points (0,2)(0, 2) and (1,1)(1, -1). This is the graph of the equation y=3x+2y = -3x + 2.

Here are some related questions:

  1. How would you graph y=2x+1y = 2x + 1?
  2. What happens to the graph if the slope is positive?
  3. How do you find the x-intercept of the equation y=3x+2y = -3x + 2?
  4. What is the effect of changing the y-intercept on the graph?
  5. How would the graph change if the slope were steeper, say y=5x+2y = -5x + 2?

Tip: The slope determines the steepness and direction of the line, while the y-intercept determines where the line crosses the y-axis.
