Instead of doing your problem for you, I'll do one exactly like it in every
detail so you can do yours yourself using this as a model. The problem I
will do is this

The slope of the line passing through P(2,6) and Q(x,10) is -4/7. What is the value of x?
Use the slope-intercept form:



Wehere , , 



Now we substitute y=10





Multiply both sides by 7













Answer: -5.

Now do yours exactly the same way.
