How do you graph f(x)=-5x
Plot 2 points and draw a line thru them.
If x = 0, y = -5*0 = 0
If x = 1, y = -5*1 = -5
----
Plot (0,0) and (1,-5) to get:

------------------------------------------------------------------------
f(x)=(1/2)x + 4
If x = 0, y = (1/2)*0+4 = 4
If x = 2, y = (1/2)2+4 = 5
--------------------------------
Plot (0,4) and (2,5) to get:
