Math Problem Statement
graph y = -3x + 2
Solution
To graph the equation , follow these steps:
1. Identify the Slope and Y-intercept
The equation is in the slope-intercept form , where:
- is the slope.
- 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 .
3. Use the Slope to Find Another Point
The slope 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 , move 1 unit to the right to , then 3 units down to .
4. Plot the Second Point
Plot the second point on the graph.
5. Draw the Line
Draw a straight line through the two points and . This is the graph of the equation .

Here are some related questions:
- How would you graph ?
- What happens to the graph if the slope is positive?
- How do you find the x-intercept of the equation ?
- What is the effect of changing the y-intercept on the graph?
- How would the graph change if the slope were steeper, say ?
Tip: The slope determines the steepness and direction of the line, while the y-intercept determines where the line crosses the y-axis.
