Answer:
k = ½
Equation => [tex] y = \frac{1}{2}x [/tex]
Step-by-step explanation:
Constant of proportionality (k) = y/x
Using a point on the graph, (6, 3),
k = y/x = 3/6 = ½
k = ½
Equation of the line:
Plug in the value of k into [tex] y = kx [/tex] (slope-intercept form of equation for proportional relationship)
Thus:
[tex] y = \frac{1}{2}x [/tex]
