Answer 1

Do you remember how the slopes of two perpendicular lines are related?

Answer 2

yes their negative reciprocal

Answer 3

Ok, so you have all the information you need: the slope and a point(2,1)

Answer 4

Y - 1 = 1 ( X -2 ) ,

X - Y = 1 { answer ]

Answer 5

Is it clear?

Answer 6

is the slope postive 1

Answer 7

Yes

Answer 8

yes, slope = -1/(-1)=1

Answer 9
