Question

whats the constant proportionality

Answer 1

Problem

Solution

For this case we can calculate the constant of proportionality with this formula:

$m=\frac{y_2-y_1}{x_2-x_!}$

And for this case we can use x1=6, y1=21, x2= 13, y2= 45.5

And if we replace we got:

$m=\frac{45.5-21}{13-6}=3.5$

And the answer for this case would be k=3.5
