  1. y = 4x−10 ; slope m = 4

    Parallel has same slope so slope of new line = 4

    y = 4x + b

    b = y - 4x

    Passes through (1, 13)

    b = 13 - 4(1)

    b = 13 - 4

    b = 9

    Equation

    y = 4x + 9

  2. If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
    [tex]y = 4x + c[/tex]
    sub in coorfinates (1,13)
    [tex]13 = 4 + c[/tex]
    So C=9.
    [tex]y = 4x + 9[/tex]
