The slope can be read directly from the equation. It is the coefficient of the x variable. Slope = -12 The final answer is: Slope = -12 You can also compute a table of values to compute the slope. Y = -12x + 15 If x = 0, y = -12 * 0 + 15 = 15 If x = 1, y = -12 * 1 + 15 = -12 + 15 = 3 The slope can be computed from these two x,y values: (x, y) (0, 15) (1, 3) slope = “rise” over “run”, or “rise” DIVIDED BY “run” slope = (change in “y” values)/(change in “x” values) slope = (y₂ - y₁)/(x₂ - x₁) The x-y coordinates of the two points are: (0, 15) and (1, 3). The slope will be calculated as the change of “y” when x increases. In this case “x” will increase from 0 to 1 (left to right). slope = (y₂ - y₁)/(x₂ - x₁) slope = (3 - 15)/( 1 - 0) slope = (-12)/( 1) slope = -12 Thanks for writing.
