Use the definition of slope:
slope=rise%2Frun
When you have two points (x%5B1%5D,y%5B1%5D) and (x%5B2%5D,y%5B2%5D%29),
Rise = y%5B2%5D-y%5B1%5D and Run = x%5B2%5D-x%5B1%5D.
Using the information from the problem, we have:
slope=rise%2Frun
2=%287-3%29%2F%28x-4%29
2=4%2F%28x-4%29
%28x-4%29%2A2=4%2Fcross%28x-4%29%2Across%28x-4%29
%28x-4%29%2A2=4
%28x-4%29=2
x=6
