How do you write the sum of b and 4?

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
