Answer:

Step-by-step explanation:
We are asked to find the length of a segment or the <em>distance</em> between the 2 points. The formula for distance is: 

where (x₁ y₁) and (x₂, y₂) are the points. We are given the points ( -5, 4) and (6, -3). If we match the number and the corresponding variable, it is:
- x₁= -5 
- y₁= 4 
- x₂= 6 
- y₂ = -3 
Substitute the values into the formula. 

Solve inside the parentheses. 
- 6--5 (Back to back negative signs become a positive)= 6+5 =11 
- -3-4= -7

Solve the exponents. 
- (11)²= 11*11= 121
- (-7)²= -7*-7= 49 

Add. 


Even though it's not specified, we could round to the nearest hundredth to make the answer more concise. The 8 in the thousandth place tells us to round the 3 to a 4 in the hundredth place. 

The length of the segment is <u>√170</u> or approximately <u>13.04. </u>
