Let's find the value of the given expression [tex]\( \frac{x^2 y}{-7} \)[/tex] using the given values [tex]\( x = -1 \)[/tex] and [tex]\( y = 9 \)[/tex].

1. First, calculate [tex]\( x^2 \)[/tex]:
[tex]\[ x^2 = (-1)^2 = 1 \][/tex]

2. Next, multiply [tex]\( x^2 \)[/tex] by [tex]\( y \)[/tex]:
[tex]\[ x^2 \cdot y = 1 \cdot 9 = 9 \][/tex]

3. Finally, divide the product by [tex]\(-7\)[/tex]:
[tex]\[ \frac{9}{-7} = -1.2857142857142858 \][/tex]

So, the value of the expression [tex]\( \frac{x^2 y}{-7} \)[/tex] is [tex]\(-1.2857142857142858\)[/tex].
