Answer 1

let the equation of live is y=mocte or y-moc-czo is 19,- myoci-cl = 255 Jitma 17-mx5-cl = 255 tma (7-5m-c) =2550 (5 tma) 17-5m-C)2 = 20 (1+m2) 4) ne passes through (-5,-3) -3= mx-stC c=-3x5m - E) putting (2) in () (7-5m-1-3 tsm)] 20 (14m2) [7-5m+35mj2 = 20 (loma) (por low j2 = 20 (17m2) 100 ci-my? = 20114m2)
