Given the first-order function y = - 5 / 12x + 12, find the area of the figure enclosed by the image and the coordinate axis

Given the first-order function y = - 5 / 12x + 12, find the area of the figure enclosed by the image and the coordinate axis

Let y = - 5 / 12x + 12 = 0, calculate x = - 1, then the intersection coordinates of the image and the horizontal axis are (- 1,0),
Let x = 0, then y = - 5 / 12x + 12 = - 12 / 5, then the coordinates of the intersection of the image and the vertical axis are (0, - 12 / 5)
Area s = (1 * 12 / 5) / 2 = 6 / 5
