Answer: x² = 4y -8
Step-by-step explanation: The equation of the set of points which are equidistant from a point and from a line is a parabola. In this case:
F ( 0 , 2 ) The parabola open upwards, so is of the form
p = 1
( x - h )² = 4*p* ( y - 2)
x² = 4 * ( y - 2 )
x² = 4y -8
This is simply what I wrote for my assignment, sorry I am a bit late.
<em>It was confusing when she took out the negative and postive pairs, but then I soon knew that the negative tiles are like subtracting positive tiles. Then once she got the total I was amazed with how easy it was to find out the value of x.</em>
hope this helps! <3

∠TSU=∠RQU
∠TUS=∠RUQ
TU=RU
The absolute value of x, written as |x|, is the distance from x to 0 on the number line.
If the distance is larger than 2, then we know
|x| > 2
If |x| > 2, then either x > 2 or x < -2
If x > 2, then we can subtract 2 from both sides to get...
x > 2
x-2 > 2-2
x-2 > 0
x + (-2) > 0
-2 + x > 0
So -2+x is positive. The original statement is true.
