I believe it would be a to X is 20 units because A to B is 10 units so a to X would make sense if it was 20 units hope this helps!
We can see that the only change that occurs to the points after the reflection is that the x-values are negated, because -4 becomes 4 and -6 becomes 6. And the only reflection that causes only a negation in the x-values is a reflection over the x-axis.
Hope this helps
<h3>
1. Compare Functions B and L by determining which one has the greater rate of change.</h3>
The rate of change is expressed as the ratio between a change in one variable relative to a corresponding change in another. On the other hand, a linear function is given as the form:

And
is the rate of change we are looking for. For Function B we have a Table and the slope can be found by choosing two points, therefore:

As you can see
has a rate of change of 6 while the function of the table has a rate of change of 3.
<em> In conclusion,</em>
<em>has the greater rate of change</em>
<h3>
2. which one has a greater y-intercept?</h3>
We need to get the equation that rules the points given on the table. Two-Point Form of the Equation of a Line is:

As you can see
has a y-intercept of
while the function of the table has a y-intercept of 
<em> In conclusion,</em>
<em>also has the greater y-intercept</em>
it would be B i think i hope this helps
