Given:
Line A: 
Line B: 
Line C: 
Line D: 
To find:
Which lines are perpendicular
Solution:
General equation of a line:
y = mx + c
where m is the slope and c is the y-intercept.
Slope of line A = 
Slope of line B = 
Slope of line C = 2
Slope of line D = 
<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>


Negative reciprocal of
is 2.
Therefore line B and line C are perpendicular lines.
Step-by-step explanation:
so,
y = -9x + 2
now we need to transform this equation that actually x is calculated out of y.
and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.
so,
y = -9x + 2
y - 2 = -9x
x = -(y - 2)/9 = (-y + 2)/9
=> for a formal function definition
y = (-x + 2)/9
The greatest common factor is 18
Then you divide 18 by 96 then 80
80/16=5
96/16=6
