Find the angle of slope of the straight line joining the points P(-3, 2) and Q(5...



Dicussion (1)

  • The formula for angle of a slope is m=tan μ(angle)
    m= (y2-y1)/x2-x1
    m= (5-2)/5-(-3)
    3/8
    Therefore, m=tan μ (angle)
    3/8=tan μ
    μ= arc tan 0.375
    μ= 20.556
    approximately 21⁰
