The graphs of functions f(x) and g(x) = f(x) + k are shown below. graph of line f of x going through ordered pairs 0, 1 and 2, 6. graph of line g of x going through ordered pairs 0, negative 1 and 2, 4. the value of k is

The problem is asking to find the value of K according to the graph that has been given and also base on the the function. In my further calculation,  I came up with a solution that leads to the answer that the value of K is -2. I hope you are satisfied with my answer and feel free to ask for more 

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
