    function

    A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner.

    Step-by-step explanation:

    Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f (x) = 5x + 4?

    Solution:

    Given,

    f (x) = 5x + 4

    The general form of a linear equation is,

    f (x) = mx + c

    So,

    Slope = m = 5

    Substitute f (x) = 0,

    0 = 5x + 4

    5x = - 4

    x = - 45

    The x-intercept is (-45, 0)

    Substitute x = 0,

    f (x) = 5 (0) + 4

    f (x) = 0 + 4

    f (x) = 4

    The y-intercept is (0,4)
