Answer: The equation of the trend line is y = -2x + 24.
First, we need to find the slope. The slope is the change in y over the change in x between the points. Our points move down 4 units while moving right 2 units. So our slope would be -4/2 or just -2.
Second, we need to find the y-intercept. We are lucky because the y-intercept can be see clearly in the graph. It is (0, 24).
We can put the slope and y-intercept together to get the equation:
y = -2x + 24.
