The constant of proportionality of the proportional relationship is: 3.5.
How can You Find the Constant of Proportionality of a Proportional Relationship?
A proportional relationship between two variables, x and y, can be expressed in slope-intercept form as, y = kx, where k is the constant of proportionality.
The constant of proportionality is therefore determined using the formula, k = y/x.
Given the graph above, we can use the point on the line, (1, 3.5) to find the constant of proportionality.
Constant of proportionality, k = y/x = 3.5/1
Constant of proportionality, k = 3.5.
Therefore, the constant of proportionality of the proportional relationship is: 3.5.
