Line \(L_1\) represents the graph of \(3x + 4y = -14\). Line \(l_2\) passes through the point\((-5,7)\) , and is perpendicular to line \(L_1\) . If line \(l_2\) represents the graph of \(y=mx +b\), then find \(m+b\).

Find the value of B - A if the graph of Ax + By = 3 passes through the point (-7,2), and is parallel to the graph of x + 3y = -5.

(I=Just a little tip, dont procrastinate, its really bad and its what got me here. Very stressful, dont reccomend :/)

Thanks in advance!!!
