Indsay used two points, (x1,y1) and (x2,y2), to find the equation of the line, y = mx + b, that passes through the points. first, she used the definition of slope and determined that the value of m is (y2-y1/x2-x1). given this information, which expression must represent the value of b?

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.
