Full solution

Q. Is (7,8)(7, 8) a solution to the equation y=x−1y = x - 1?\newlineChoices:\newline(A)yes\newline(B)no
  1. Identify values of x and y: Step 11: Identify the values of xx and yy in the point (7,8)(7,8).\newlinex=7x = 7\newliney=8y = 8
  2. Substitute values into equation: Step 22: Substitute the values into the equation y=x−1y = x - 1.\newlineSubstitute 77 for xx and check if 88 equals 7−17 - 1.\newlineCalculation: 8=7−18 = 7 - 1
