To find the slope and the equation of a proportional relationship from a graph, we typically follow these steps:
-
Finding the Slope: The slope (m) can be computed as the change in the y-values divided by the change in the x-values between two points on the line. If you have coordinates of two distinct points from the graph, use the formula:
\[ m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1} \]
-
Writing the Equation of the Line: In a proportional relationship, the equation of the line can be expressed in the form:
\[ y = mx \]
where m is the slope you found previously.
If you can provide the specific graph details or the coordinates of points from the graph, I could help you calculate the exact slope and write the equation for that line.
