Is the point shown on the graph a solution for the simultaneous inequalities y>6x−4 and y≤3x+2 ? Enter 1 for yes or 2 for no.

(2, 8)

1 answer

To determine if the point (2, 8) is a solution to the inequalities \( y > 6x - 4 \) and \( y \leq 3x + 2 \), we can substitute \( x = 2 \) and \( y = 8 \) into both inequalities.

  1. For the inequality \( y > 6x - 4 \): \[ 8 > 6(2) - 4 \] \[ 8 > 12 - 4 \] \[ 8 > 8 \] This is not true since \( 8 \) is not greater than \( 8 \).

  2. For the inequality \( y \leq 3x + 2 \): \[ 8 \leq 3(2) + 2 \] \[ 8 \leq 6 + 2 \] \[ 8 \leq 8 \] This is true since \( 8 \) is equal to \( 8 \).

Since the point (2, 8) satisfies one inequality but does not satisfy the other, it is not a solution to the simultaneous inequalities.

Therefore, the answer is 2 (no).
