@jim_thompson5910 I need help on 3

Answer 6

in #3, you're just comparing and contrasting slopes

any slopes that are equal represent parallel lines

any pairs of slopes that multiply to -1 represent perpendicular lines

Answer 7

example

AB || XT since they both have a slope of 1/3

also

AB is perpendicular to TJ since the two slopes multiply to -1
