Concept Used:


The equation of the line with intercepts a and b is


Given:


Here a + b = 7, b = 7 – a


Explanation:


The line is passing through (-3, 8).



Substituting b =7 – a, we get




a2 + 4a – 21 = 0


(a – 3)(a + 7)= 0


a = 3 ( since, a can only be positive )


Substituting a = 3 in equation (i) we get,


b = 7 – 3 = 4


Hence, the equation of the line is
