Question

Show that the line joining the points P (0, 1, 2) and Q (3, 4, 8) is parallel to the line
joining the points R (- 2, 3/2, -3) and s( 5/2,6,6)​

Answer 1

Step-by-step explanation:

parallel lines means having same slope.

slope is denoted by m.

m= y2-y1/x2-x1

for point R (x1,y1,z1)

for point s(x2,y2,z2)

similarly for P,Q.

SLOPE OF PQ will be:

m=4-1/3-0

m=1

slope of RS:

m=6-(3/2)/(5/2)-(-2)

=4.5/4.5

m=1.

both slope are equal so parallel
