Formulas (Analytic Exam Success Roadmap: Comprehensive Study Guides
division of line segment x = (x1r2+x2r1)/r1+r2 y = (y1r2+y2r1)/r1+r2 Location of midpoint x = (x1 + x2)/2 y = (y1 + y2)/2 point slope form y-y1=m(x-x1) two-point form y-y₁=(y₂-y₁)/(x₂-x₁)×(x-x₁) slope-intercept form y=mx+b intercept form x/a + y/b = 1 slope of the line m = -A/B Angle between two lines tanΘ = (m1-m2)/(1+m1*m2), m's are slopes of two lines Distance of a point from a line Ax+By+C=0 d = (Ax1+By1+C)/+-(sqrt(A^2+B^2))
