now, with that template in mind, let's check this one
A = -1, reflection over the x-axis.
B = 1, C = +3, C/B = +3/1 = +3, horizontal shift to the left of 3 units.
D = 5, vertical shift up of 5 units.
If the entire school had 720 students can use this data to estimate how many of them would say that it takes them more than 10 m

<h3>Therefore they are perpendicular.</h3>
Step-by-step explanation:
A equation of line is
y =mx +c
Here the slope of the line is m.
Given equations are
x - 2y = 18
⇔-2y = -x +18
............(1)
and 2x + y = 6
⇔y = -2x +6 ............(2)
Therefore the slope of equation (1) is=
Therefore the slope of equation (2) is= -2
If two lines are perpendicular, when we multiply their slope we get -1.
therefore,
=
. (-2) = -1
Therefore they are perpendicular.
