Answer:
Step-by-step explanation:
We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_

Standard form of equation of line = 
Given points = (7, -3) and (4, -8)
Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -

[∵ (-)(-)=(+)]
Or
Hence, the required equation :-
