To determine if the coordinates (9, -10) make the inequality y < (-1/9)x - 7 true, substitute the values x = 9 and y = -10 into the inequality:
-10 < (-1/9)(9) - 7
Simplifying the right side:
-10 < -1 - 7
-10 < -8
Since -10 is less than -8, the inequality y < (-1/9)x - 7 is true when x = 9 and y = -10.
Does(9, –10)maketheinequality y < –1/9x − 7 true?
