Line QR contains (2, 8) and (3, 10) Line ST contains points (0, 6) and (−2, 2). Lines QR and ST are
I have a hard time undestanding this math because i have a learning disability and i really could use some help id like to graduate next year so yeah.
Lines are either parallel, perpendicular or intersecting.
If the slopes of the two lines QR and ST are equal, then the lines are parallel m1 = m2
If the slopes of the line are reciprocal inverse to each other
m2=-(1/m) then the line QR and ST are perpendicular
if none, the slopes are neither parallel or perpendicular
Find slope of line QR passing through the two points
(2, 8) and (3, 10)
the slope of line QR is m1= (10-8)/(3-2)=2/1=2
Find slope of line ST passing through the two points
(0, 6) and (-2, 2)
the slope of line QR is m2= (2-6)/(-2-0)=-4/-2=2
Since slopes of the line m1=m2=2 then the lines QR and ST are parallel
to each others.
