Question

yo help me out
Is the line through points P(–8, –10) and Q(–5, –12) perpendicular to the line through points R(9, –6) and S(17, –5)? Explain

Answer 1

find the slopes of both lines and see if they are opposite reciprocals of each other

Answer 2

i would if i knew, can you please give me the answer ill give u a medal

Answer 3

to find the slope you use this formula\[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 4

so for the first two points you get
[-12-(-10)]/[-5-(-8)]
=-2/3

Answer 5

do the same for 2nd line and compare

Answer 6
