if a line is passing through a point means, if you substitute the x and y values in the equation, then equation will be solved

so, mid point in the given problem is ( -3-5 /2 , -4+6 /2).. which is (-4,2)

if (x1,y1) and (x2,y2) are the 2 given points, mud point will be ( (x1+y1)/2 , (x2+y2)/2)

slope given is 4/5 , means 4/5 =-a/b.. in 1st option and 2nd option, slope, i.e -a/b =4/5
