To find:-
- The equation of line passing through the points (3,20) and (8,25) .
Answer:-
To find out the equation of the line , we need to find out the slope first. It can be calculated as ,

And here ,
On substituting the respective values, we have;



Hence the slope of the line is 1 . Now we may use point slope form of the line to find out the equation of the line. Point slope form of the line is,

Take any of the given two points. Here i am taking (3,20) . So here we have;
On substituting the respective values, we have;




Hence the equation of the line in standard form is x - y + 17 = 0 .
and we are done!
