Step-by-step explanation:
Given the equation

This equation consists of two parts. In the left part, there is a logarithmic function
In the right part, there is a linear function 
To solve the equation graphically, you have to plot the graphs of these two functions and find the point of intersection of these graphs.
Hence, appropriate system is

Answer:
The slope is -1/2
Step-by-step explanation:
To find the slope you have to use the formula: Δy/Δx OR change in y/change in x.
The change in y for these points is -1 (2-1)
The change in x for these points is 2 (1+2)
Then divide the change in y by the change in x. ( -1 divided by 2)
You will get -0.5 or -1/2 as your final answer for the slope.
