Based on the image, the trend line appears to have a positive slope and passes through the point (0,30). Therefore, the equation of the trend line in slope-intercept form would be:
y = mx + b
where m is the slope and b is the y-intercept.
By observing the image, we can estimate the slope of the trend line to be approximately 2/3. The y-intercept is given as 30.
Therefore, the equation in slope-intercept form of the trend line is:
y = (2/3)x + 30
