  1. Straight line equations:

    y = mx + b

    m = slope

    b = y-intercept ( Point on the graph where x is zero )

    Difference between y coordinates is constant = 15

    29 - 14 = 15
    44 - 29 = 15
    59 - 44 = 15

    Slope = 15

    y-intercept = y coordinate when x = 0

    y-intercept = 14

    So :

    m = 15

    b = 14

    y = mx + b

    y = 15 x + 14
