Answer: D
Step-by-step explanation: There are no constants in this expression.
There will be no odd number in the units place for any product of 8.
In linear relationships, any given change in an independent variable will always produce a corresponding change in the dependent variable.
I believe,
since... slope = (y2-y1)/(x2-x1)
so... slope = (-1+5)/(-1-2)
slope = (4)/(-3) or.. -.75
