Well -15 divided by 3 is -5, so -5\5 = -1. But that's not one of the answers...
<em>When evaluating 
then we get that the expression is 11</em>
<h2>
Explanation:</h2>
As I understand the expression is the following:
Let's call, that expression as 
So we are asked to find the value of the expression when . In other words, we need to substitute , so:
So <em>when evaluating then we get that the expression is 11</em>

Answer:
The gradient of the line segment between the two points is -1
Step-by-step explanation:
The gradient of the line segment between two points is also known as the slope,
We can find this by using the formula; y₂ - y₁ / x₂ - x₁
The points given to us are;(-1,2) and (-2,3).
This implies x₁ = -1 , y₁=2 x₂ = -2 y₂= 3
We can now proceed to insert our values into the formula;
Gradient = y₂ - y₁ / x₂ - x₁
= 3 - 2 / -2-(-1)
= 1 / -2 + 1
=1/-1
Gradient = -1
Therefore the gradient of the line segment between the two points is -1
