Answer 1

7
`\displaystyle \boxed{5}\:\boxed{-4}`

6
`\displaystyle -1`

5 ○ Perpendicular

Explanation:

7 Halfway in between −2 and −6 is −4, and halfway in between 0 and 10 is 5, so you will have this:

`\displaystyle (5, -4)`

6 Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so line r also has a slope of −1.

5 Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE RATE OF CHANGES [SLOPES], so −8⁄9 indeed becomes 1⅛ [or 9⁄8], therefore lines r and q are perpendicular.
