I believe it is false because it only passes through the y-axis not the x-axis.
There was 11.54% decrease in attendance.
Step-by-step explanation:
Attendance in 2014 = Old value = 650
Attendance in 2015 = New value = 575
Change = New value - Old value
Change = 575 - 650 = -75
The negative sign indicates a decrease in attendance.
Decrease percentage = 

Rounding off to nearest hundredth
Decrease percent = 11.54%
There was 11.54% decrease in attendance.

They are the same slope
they are negative inversees (they multily to get -1)
2
-1/2
use the square viewer (on TI)
The relationship between the slopes of two lines that are parallel is they are the same.
The relationship between the slopes of two lines that are perpendicular is they are negative inverses of each other (they multiply to -1).
A line that is parallel to a line whose slope is 2 has slope 2.
A line that is perpendicular to a line whose slope is 2 has slope -1/2.
What must be done to make the graphs of two perpendicular lines appear
to intersect at right angles when they are graphed using a graphing
utility?
Answer:
(1)
Step-by-step explanation:
We will try:
(1) y =
x => 2 = 2 (seems legit)
(2) y = 4x => 2 = 32 (nope)
(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)
(4) y =
x - 2 => 2 = 2 (like the above)
Since the equation says "cos(x-2)", we know that the horizontal displacement is 2 units.
