y= -7x/4 -1
(-4 ) y = -6. ( -4,6)
(0, )y=-1. ( 0,-1)
(4, ) y= -8. (4,-8)

        To the composer of this problem


Along all your composition (I mean this problem) you mistakenly call the object as "the linear equation".

For your information: in this context, it is not a linear equation. It is a linear function.

The correct name for this object in the given context is "a linear function", not "a linear equation".

Substitute each x value and evaluate corresponding y value.
x             y=-(7/4)x-1
---------------------------------------
 -4             -(7/4)*4-1
  0             -(7/4)*0-1
  4             -(7/4)*4-1


But in fact you can read the slope and the y intercept from the equation for
graphing the function.
You finish!
