Answer:
The constant of Proportionality is 7
Explanation:
In simpler terms, the C.O.P. is just the slope of a line as the slope is defined as the steepness of the line. Using the equation y = 7x, we can determine it is in Slope-intercept form (y = mx + b), in which 'm' is the slope. The 'b' value is actually the y-intercept which if there is no value in the 'b' location, we know the coordinates for the y-intercept are (0, 0). This deduces that the C.O.P. for y = 7x is 7.
