<h2>Part a)</h2>
You can name planes by one letter or using three points belonging to it that are <u>not</u> on the same line.
Another name for plane X could be:
- Plane ABF, Plane BCF or Plane ACF. You may also get different names by reordering the three letters.
<h2>Part b)</h2>
Coplanar means 'on the same plane'.
The points on the same plane as point A are:
<h2>Part c)</h2>
Collinear means 'on the same line'.
Other points on the same line as point C are:
<h2>Part d)</h2>
The line that intersects ED is:
- AC, it can be also named AB or BC.
As we know,

now, let's plug the given values to find a² + b²
Answer:
T^75
Step-by-step explanation:
3 times 5 = 15
5 times 15 = 75
Answer:
y = x - 5
Step-by-step explanation:
The equation of the line parallel to the line
is
.
That is, equations of parallel lines differ only by constant.
The given equation is 
This is written as 
Therefore, the equation of the line parallel to this line is given by 
The value of c is determined using the point given.
Substituting the point (3,-2) we get:


Therefore, the equation of the line becomes y = x - 5.
