    Answer:

    y = x + 1

    Step-by-step explanation:

    find slope first:

    (4-2) / (3-1) = 2/2 or 1

    now find the y-intercept, or ‘b’ by using one of the two given points and the slope

    2 = 1(1) + b

    2 = 1 + b

    1 = b

    equation in slope-intercept form:

    y = 1x + 1  or  y = x + 1
