Since the point is (1,k) this means that x=1 and y=k


2y%2B5x=10 Start with the given equation


2k%2B5%281%29=10 Plug in x=1 and y=k


2k%2B5=10 Multiply


2k=10-5 Subtract 5 from both sides


2k=5 Subtract


k=%285%29%2F%282%29 Divide both sides by 2 to isolate k.


k=2.5 Divide.

Answer:

So the answer is k=2.5


This means that the point is (1,2.5) which looks like
