Question 447764
Substitute each x value and evaluate corresponding y value.
<pre>
x             y=-(7/4)x-1
---------------------------------------
 -4             -(7/4)*4-1
  0             -(7/4)*0-1
  4             -(7/4)*4-1
</pre>
  
But in fact you can read the slope and the y intercept from the equation for 
graphing the function.

You finish!
