Question

Does the point (2, 9) satisfy the inequality y ≤ 3 x + 1 ?

Answer 1

A point is written using the form (X,Y), so the first number is the X and the second number is the Y.

Replace x and Y in the given equation with the given point:

y ≤ 3x+1

9 ≤ 3(2) +1

9 ≤ 6 +1

9 ≤ 7

9 is not less than or equal to 7, so the point (2,9) does not satisfy the inequality.
