<u>Answer:</u>
- Slope = 27/11
- AB = 29.15 u
<u>Step-by-step explanation:</u>
<u>Given :- </u>
- Two points are given to us .
- The points are A(7,15) and B(18,42) 
<u>To Find</u> :- 
- The slope of the line .
- The length of line AB .
We can find the slope of the line passing through the points  and
 and  as ,
as , 
 
 
- Plug in the respective values , 
 
 
<u>Hence the slope of the line is 27/11 .</u>
 
 
<u>Finding the length of AB :-</u>
- We can find the distance between them by using the Distance Formula .
 
 
<u>Hence the length of AB is 29.15 units .</u>
