QuestionFind the equation of the line at the point $(x=-4, y=4)$ and simplify: $-5x - 2y + 9$ .

Studdy Solution

STEP 1

Assumptions1. We are given a linear equation $-5x -y +9$ . . We are asked to find the value of this expression at the point $x = -4, y =4$ .

STEP 2

We need to substitute the given values of $x$ and $y$ into the equation. $-5x -2y +9 = -5(-4) -2(4) +9$

STEP 3

Now, we perform the multiplication in the equation.
$=20 -8 +9$

STEP 4

Finally, we perform the addition and subtraction to find the value of the expression at the given point.
$=20 -8 +9 =21$ So, the value of the expression $-x -2y +9$ at the point $x = -4, y =4$ is21.
