Answer» Answer: Answer: The solutions of y = 3x - 1 are (1, 2) and (0, -1) We will SUBSTITUTE x-coordinate and y-coordinate in the equation y = 3x - 1 to check if the given points are the solution of the equation. https://www.cuemath.com › questions Step-by-step explanation: (a) Substitute 2 for x and -3 for y in y = 3x - 1 -3 = 3 (2) - 1 -3 = 6 - 1 -3 = 5 This is not TRUE. So, (2, -3) is not a solution of y = 3x - 1 (b) Substitute 1 for x and 2 for y in y = 3x - 1 2 = 3 (1) - 1 2 = 3 - 1 2 = 2 This is true. So, (1, 2) is a solution of y = 3x - 1 (c) Substitute 0 for x and -1 for y in y = 3x - 1 -1 = 3 (0) - 1 -1 = 0 - 1 -1 = -1 |
