Question

show that the line joining the points A(2,-3)
and B(-5,1) is parallel to the line
Joining the point c (7,-1)and D (0,3)and
perpendicular to the line joining E (4,5)
and F(0-2)

Answer 1

Answer:

Step-by-step explanation:

if both line are parallel then their slope must be equal ..

formula of finding slope from given coordinates are ..y2 -y1 / x2 - x1

now , slope of first line = slope of second line

1 -(-3) /-5 - 2 = 3-(-1) /0 -7

-4/7 = -4/7
