    Algebra: Finding the Value of y and x in a Linear Function

    Разъяснение: To find the value of y when x = -22 in the function y = -2/11x - 3, we substitute the value of x into the equation and calculate the corresponding value of y. Substituting x = -22, we have:

    y = -2/11 * (-22) - 3
    y = 44/11 - 3
    y = 4 - 3
    y = 1

    Therefore, when x = -22, the value of y is 1.

    To find the value of x when y = -5, we substitute the value of y into the equation and solve for x. Substituting y = -5, we have:

    -5 = -2/11x - 3
    -2/11x = -5 + 3
    -2/11x = -2
    x = (-2 * 11) / -2
    x = 11

    Hence, when y = -5, the value of x is 11.

    To find the coordinates of the points of intersection between the graph of this function and the coordinate axes, we set x and y equal to zero and solve for the other variable.

    x-intercept: Setting y = 0, we have:
    0 = -2/11x - 3
    2/11x = -3
    x = (-3 * 11) / 2
    x = -33/2

    Therefore, the x-intercept is (-33/2, 0).

    y-intercept: Setting x = 0, we have:
    y = -2/11 * 0 - 3
    y = -3

    Thus, the y-intercept is (0, -3).
