  1. To find the distance between the points (-5, -10) and (2, 4), we can use the distance formula:

    [

    d = sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2}

    ]

    Here, ((x_1, y_1) = (-5, -10)) and ((x_2, y_2) = (2, 4)).

    1. Calculate (x_2 – x_1):

    [

    2 – (-5) = 2 + 5 = 7

    ]

    2. Calculate (y_2 – y_1):

    [

    4 – (-10) = 4 + 10 = 14

    ]

    3. Now apply the distance formula:

    [

    d = sqrt{(7)^2 + (14)^2} = sqrt{49 + 196} = sqrt{245}

    ]

    4. Simplify (sqrt{245}):

    [

    sqrt{245} approx 15.65

    ]

    So, the distance between the points is approximately 15.65.

  2. To find the distance between the points (-5, -10) and (2, 4), we can use the distance formula:

    [

    d = sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2}

    ]

    Here, ((x_1, y_1) = (-5, -10)) and ((x_2, y_2) = (2, 4)).

    1. Calculate (x_2 – x_1):

    [

    2 – (-5) = 2 + 5 = 7

    ]

    2. Calculate (y_2 – y_1):

    [

    4 – (-10) = 4 + 10 = 14

    ]

    3. Now apply these values in the formula:

    [

    d = sqrt{(7)^2 + (14)^2} = sqrt{49 + 196} = sqrt{245}

    ]

    4. Calculate (sqrt{245}):

    [

    sqrt{245} approx 15.65

    ]

    So, the distance between the points is approximately 15.65.
