If an is 18 and as is half its length it would be 9, AD = 9

Point-slope form is
, where
is the slope and
is a point on the line.
Substitute in the values. 
Simplify the negative subtraction to addition. 
Hello there!
In order to graph the solution, we need to solve it first.
So let's start....
3/7(35x - 14) ≤ 21x/2 + 3
15x -6 ≤ 21x/2 + 3
15x - 21x/2 ≤ 3 + 6
9x/2 ≤ 9
x ≤ 9* 2/9
x ≤ 18/9
x ≤ 2
See the picture for the graph
Please let me know if you have questions about the answer.
Thanks!
