Answer:
7 [tex]\displaystyle \boxed{5}\:\boxed{-4}[/tex]
6 [tex]\displaystyle -1[/tex]
5 ○ Perpendicular
Step-by-step explanation:
7 Halfway in between −2 and −6 is −4, and halfway in between 0 and 10 is 5, so you will have this:
[tex]\displaystyle (5, -4)[/tex]
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.
