$(10, - 86)$ $(10,-86)$

Consider $(x, y) = (10, - 86)$ $(x,y)=(10,-86)$

Set $x = 10$ $x=10$

$y = - 9 x + 4 \to y = - 9 (10) + 4 = - 86$ $y=-9x+4" "->y=-9(10)+4 = -86$

This is a match

The question uses the wording "ordered pair" $\to$ $->$ singular

So there is only 1 ordered pair we are required to find
