Question

let me know the answer

Answer 1

general equation of line in intercept form is
$(x \div a) + (y \div b) = 1$
y intercept =b=5
$(x \div a) + (y \div 5) = 1$
since line passes through (1,3)..hence will satisfy
$(1 \div a) + (3 \div 5) = 1 \\ (1 \div a) = 2 \div 5 \\ a = 5 \div 2$
put in second eqn

Answer 2

this is ur required result
