Just multiply numerator and denominator by the same number
Rate of change is -2 because you can do rise over run to find the constant rate of change, and since you are going down you have a negative slope.
→4(2) which can be referred to as 4 + 4
→14 (4)<span>= 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 </span> which also equal to → 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 +4 + 4 +4 +4 + 4 +4 +4
6m+8
This is because you have to distribute (multiply) the 2 to each number inside the parentheses.
Hope this helped!
An undefined term in geometry means that such terms
cannot be explained properly. The examples of undefined terms in geometry are
point, line, and plane. A point is a dimensionless term, which has no length or
width or thickness. Similarly a line or a plane also has no width. A line can
be extended in two directions, while a plane can be extended in all directions.
<span>On the other hand undefined terms combines in a meaningful
way, i.e. when a line crosses another lines, it forms an angle. Thus angle is a
defined term in geometry. </span>
