Here is how i solved it hope it helps
Line j passes through points (9, 6) and (6, 8). Line k passes through points (7, 9) and (5, 6). Are line j and line k parallel o
1 answer:
9514 1404 393
Answer:
perpendicular
Step-by-step explanation:
A graph shows the lines are not parallel. The lines are perpendicular.
__
j has a slope of -2/3 (down 2 for each 3 to the right)
k has a slope of 3/2 (up 3 for each 2 to the right)
These slope values have a product of 1, typical of perpendicular lines.

Answer:
given,
selling price (sp)=rs 5 ×30
=rs 150
now, gain %=20%
cost price (cp)=
therefore cp= rs125
now,
again in 2nd case
sp= rs 27×5
therefore sp=rs 135
and cp= rs125
now, sp>cp so,
or, gain=
therefore gain %= 8%.... is answer

Required Equation is
Given: A line passing through and
Slope = =
Equation of line is:
Where b is y intercept
for value of b
⇒ b = -1
and Equation of line is:
For another parallel line that passes through the point (-3,0)
c = 2
then the equation is:
