Question

Calculate The Constant of Proportionality (k) and Write an Equation for the line in the Graph Below:

Answer 1

Answer:

k = ½

Equation => $y = \frac{1}{2}x$

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 $y = kx$ (slope-intercept form of equation for proportional relationship)

Thus:

$y = \frac{1}{2}x$
