Step-by-step explanation:
y = -5x - 1 should be your function.
Check. Plug in the x to get the desired y
9 = -5(-2) - 1
9 = 10 - 1
9 = 9 (correct)
4 = -5(-1) - 1
4 = 5 - 1
4 = 4 (correct)
-1 = -5(0) - 1
-1 = 0 - 1
-1 = -1 (correct)
etc.

Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression
Justification:
1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.
2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.
</span>
No. The points don’t connect in a Straight line
