The equation of a line that passes through (0, 0) is y = x, where the two variables x and y have always the same values.
Any variables can be shown on a graph.
The vertical line passing through the origin
-2.25
To identify the constant of proportionality in a graph, look for a linear relationship between the two variables, typically represented as a straight line passing through the origin (0,0). The constant of proportionality is the slope of this line, calculated by choosing two points on the line, finding the difference in their y-values, and dividing it by the difference in their x-values (rise over run). This value represents the ratio of the two variables and remains constant throughout the graph.
The graph is a straight line, passing through the origin, with a slope equal to the speed of the wave.
