    Answer:

    (0,-5)

    Step-by-step explanation:

    The given function is :

    y =  - 5 {(0.5)}^{x}

    We want to find the point where the graph touches the y-axis.

    At this y-intercept, the x-value is zero.

    So we put x=0 into the equation to obtain:

    y =  - 5(0.5)^{0}

    We evaluate exponents to get:

    y =  - 5(1)

    y =  - 5

    The function crosses the y-axis at (0,-5).
