1.	Determine whether the function is linear or nonlinear. The curve of the function has the points (-2, -14), (-1, -8), (0, -2) and (1, 4). If it is linear, determine the slope.
Answer» The given function is linear in nature, and has a slope equal to 6. The slope of a line is defined by the change in vertical direction divided by the change in the horizontal direction. Trigonometrically, it is given by tanθ, whereθ is the angle between the x-axis and the line in the anticlockwise direction.
