Answer:
K=1.25
Step-by-step explanation:
Firstly, an intersection stated will be regarded as a solution to an equation, so it is easy for anyone to plug the x and y coordinate into a function.
You can take y=1/2x+k and add (-2,1) to the corresponding values as follows.
(1)=1/2(-2)+k
And simplify
1=1/-4+k
Subtract (-1/4) from both sides
1.25=k
If you are required to, convert 1.25 to fraction form: 1 and 1/4 OR 5/4
