In order to find the rate of change, we can calculate the difference in y-values for any two points and divide it by the difference in x-values. Let's choose the points (2, 40) and (5, 10):
Rate of change = (10 - 40) / (5 - 2) = -30 / 3 = -10
The y-intercept is the value of y when x is 0. Looking at the table, we can see that there is no data for x = 0. Therefore, we cannot determine the y-intercept.
With the rate of change and y-intercept, we can write the equation of the line in slope-intercept form. However, since we do not have the y-intercept, we cannot determine the equation of the line.
