The function which can represent the height, y according to the horizontal distance, x is; Choice A; y = –3/4x + 36.
Which function can represent the height, y, according to the horizontal distance x, from the top of the stairs?
According to the task content; The railing will begin at a height of 36 inches and follow the slant of the stairs. On this note, it follows that the y-intercept of the function is 36.
Additionally, since the railings decreases 9 inches for every 12 horizontal inches, it follows that the slope, m = -9/12 = -3/4.
On this note, the required function is; A.y = –3/4x + 36
