Q. Is (−3,2)(-3,2) a solution of \newline7x+9y>−37x+9y > -3?\newlineChoose 11 answer:\newline(A) Yes\newline(B) No
  1. Substitute point into inequality: Substitute the point (−3,2)(-3, 2) into the inequality 7x + 9y > -3.\newlineCalculate 7⋅(−3)+9⋅27\cdot(-3) + 9\cdot2 to see if it is greater than −3-3.\newline7⋅(−3)+9⋅2=−21+187\cdot(-3) + 9\cdot2 = -21 + 18\newline−21+18=−3-21 + 18 = -3\newlineCheck if -3 > -3.
  2. Calculate value: Determine if the calculated value satisfies the inequality.\newlineSince −3-3 is not greater than −3-3, the point (−3,2)(-3, 2) does not satisfy the inequality 7x + 9y > -3.
