Find the 53,067 number
4,7…
159,202
Reflection makes…
the line a mirror image
Forms a x with the lines
Find the Slope:
(4,7) and (5,9)
m=2
What is the slope and y-intercept?
y=16x+13
slope = 16
y-intercept = 13
What is the Domain and Range?
y=Ix+5I
This is an Absolute Value Equation
Domain: ARN
Range: y>=0
What is x?
f(x)=5x+8
0=5x+8
8=5x
8/5=x
Is the x axis vertical or horizontal?
Horizontal
What is the Domain and Range?
f(x)={-5x if x>1
f(x)={x+6 if <= 1
Domain: ARN
Range: y<=7
Find the Slope:
(2,4) and (7,5)
m=1/5
What is the Domain and Range?
y=7IxI
This is an Absolute Value Equation
Domain: ARN
Range: y>=0
What is the Domain and Range?
y=-I8xI
This is an Absolute Value Equation
Domain: ARN
Range: y<=0
What is the Domain and Range?
(5,6) (3,8) (6,7)
Domain:{3, 5, 6}
Range:{6, 7, 8}
Translation, Dilation, or Reflection and how does it move?
y=5x
Dilation
Steeper
Is this Linear?
x: 5, 6, 7, 8, 9
y: 10, 12, 14, 16, 18
Yes, it changes +2 to y for everytime you +1 to x
Is the y axis vertical or horizontal?
Vertical
What is x?
f(x)=3x+6
0=3x+6
-6=3x
-2=x
Translation, Dilation, or Reflection and how does it move?
y=x
y=-x
Reflection
(Makes a mirroring line)
