    Answer:

    this

    Step-by-step explanation:

    Slope (m) =  

    ΔY

    ΔX

    =  

    4

    9

    = 0.44444444444444

    θ =  

    arctan( ΔY ) + 180°

    ΔX

    = 203.96248897458°

    ΔX = 1 – 10 = -9

    ΔY = 2 – 6 = -4

    Distance (d) = √ΔX2 + ΔY2 = √97 = 9.8488578017961

    Equation of the line:

    y = 0.44444444444444x + 1.5555555555556

    or

    y =  

    4 x

    9

    +  14

    9

    When x=0, y = 1.5555555555556

    When y=0, x = -3.5
