    so the equation of the line is y = 3x - 1

    Explanation:

    soln

    you find the slope

    slope=5 - - 1

    3 - 1

    =6

    2

    slope=3

    2. Then you find the equation

    y - 5 = 3

    x - 2

    3. you close multiplication

    y - 5 = 3 (x - 2)

    y - 5 = 3x - 6

    4. you correct like terms together

    y = 3x - 6 + 5

    y = 3x - 1
