Is (-1, -5) a solution to the inequality y ≤ x + 7?

1 answer

To determine if the point (-1, -5) is a solution to the inequality \( y \leq x + 7 \), we can substitute the x-coordinate and y-coordinate of the point into the inequality.

Given the point (-1, -5), we have:

  • \( x = -1 \)
  • \( y = -5 \)

Now, substitute \( x \) into the inequality:

\[ y \leq x + 7 \]

Substituting \( x = -1 \):

\[ y \leq -1 + 7 \] \[ y \leq 6 \]

Now, substitute \( y = -5 \):

\[ -5 \leq 6 \]

This statement is true. Therefore, the point (-1, -5) satisfies the inequality.

Thus, (-1, -5) is a solution to the inequality \( y \leq x + 7 \).
