A direct variation equation is one that requires y varies directly as x and looks like this in equation form:

where k is the constant of variation. If we solve this for y, we have y = kx, which happens to be a linear function... a line. k here, then, serves as the slope. So what we are given as points on a direct variation function are actually points on a line. The equation for this requires that we find the slope and then rewrite the formula accordingly. First the slope:

Now we need to write the equation by using one of the points' coordinates. I picked the first point that has an x coordinate of -9 and a y coordinate of -3. Fitting those into the slope-intercept form of a line,

which simplifies to
-3 = -3 + b and b = 0. That means that the equation of direct variation is

Answer:
0.061 
Step-by-step explanation:
Number of days  Protestants
0                           50
1                             27
2                             6
3                             16
The proportion of protestant remain calm for 2 days= number of protestant calm for 2 days/ Total number of protestant calm for 0-3 days 
The proportion of protestant remain calm for 2 days =6/50+27+6+16=6/99=0.061 (rounded to 3 decimal places)
Thus, 6.1% of protestant remain calm for 2 days.
