In this problem, we have given a function: f x, equals 4 y x plus 3 x, 4 y x plus 3, and we have to find here the equation of second line. The equation second line second line joining containing the .1 comma, f, 1 and 2 comma f; 2. The equation of second line containing the .1 f, 1 and 2 f 2. Before finding the equation of second line. First, we’ll find the slope of the slope of second line. Let m is the slope so equal, f, 2 minus f, oneby, 2 minus 1, putting the values of f 2 and f 1. We have 4 y 2 plus 3 minus 4 y 1, plus 3, divided by 2. Minus 1 is 1. So m is equal 4 by 5 minus 4 by 4 point that is 1 by 1. It will be minus 1 by 5. So this is the slope of the second line. Now we have a point. Let’S say point…
