Graphing the Linear Equation
To graph, plot these points on the grid:
- Point is on the y-axis at 2.
- Point is to the right of the origin, up at 3.
Connect these points to form a straight line representing the equation .
Would you like more details, or have any questions?
Here are five additional questions for exploration:
- How would the line change if the slope were different?
- What would the y-intercept be if it shifted up by 1 unit?
- How do you find the slope from two points on a graph?
- Can you explain how to graph lines with negative slopes?
- What if the equation was ; how would the graph look?
Tip: When graphing linear equations, always start by plotting the y-intercept, then use the slope to determine the direction and spacing of the line.
