How to find slope: y2-y1/x2-x1. This is point slope form. You can look it up if you don’t understand :)
Y intercept is when the point that passes the y line. aka when x=0.
Function 1 Slope: -1/2
Function 1 y-intercept: 1
In the second function, it is in the form of y=mx+b (look it up for further reference)
Function 2 slope: 3/4
Function 2 y-intercept: 4
Now to do the comparison questions...
1) function 2
2) function 2
3) function 1
Good luck hope this helped!!
