    Answer:

    One Answer

    Step-by-step explanation:

    Take two points like (8,2) and (12,4) and do y2-y1/x2-x1.

    4-2/12-8 = 4/2 = 2.

    Then that another point and plug it in to the equation, y = 2x + b.

    i will use (8,2). 2 = 2(8)+b. solve this and you get b= -14.

    now you found your answer. y=2x + -14.
