Answer:
1/3
Step-by-step explanation:
Take the second term and divide by the first
9/27 = 1/3
Take the third term and divide by the second
3/9 = 1/3
Check each subsequent ratio, we can see the common ratio is 1/3
slope = 0
This is a horizontal line parallel to the x- axis.
Since the slope of the x- axis is zero, then any parallel line to it has a slope of zero
2(<em>m</em>+<em>m</em>)
<em>or</em>
2<em>m</em>+2<em>m</em>
3<em>m</em>+m
4<em>m</em>+<em>m-m</em>
