Understanding Line Graphs
A line graph visually represents the relationship between two variables. In this tool, we plot a straight line on a coordinate plane using two points you provide.
Key Concepts:
- Slope (m): The slope measures the steepness and direction of a line. It's calculated as the change in y divided by the change in x (rise over run). Formula: $$m = rac{y_2 - y_1}{x_2 - x_1}$$
- Y-intercept (c): The y-intercept is the point where the line crosses the y-axis. It's the value of y when x is zero.
- Equation of a Line: The slope-intercept form of a linear equation is $$y = mx + c$$, where 'm' is the slope and 'c' is the y-intercept. For vertical lines, the equation is of the form $$x = a$$, where 'a' is a constant x-value.
Use this tool to visualize lines, understand these concepts better, and explore linear equations in a fun and interactive way!
