    Answer: (Mayadc821 wrote this anwser check theyre account for more)

    Since you know the x and y values, you just have to plug these into the linear slope-intercept equation:

    y = mx + b

    -10 = m(1) + b

    m + b = -10

    b = -10 – m

    Now that we have a value for b, we can plug this into the other equation:

    8 = m(-8) + b

    8 = -8m + (-10 – m)

    8 = -9m -10

    18 = -9m

    m = -2

    Now that we know what m is equal to, we can plug this into our first equation to get an answer for b:

    b = -10 – m

    b = -10 -(-2)

    b = -10 + 2

    b = -8

    Our final equation is y = -2x – 8
