A line has a slope of 2. It passes through the point (1,2) and (3,y). What is the value of y ?

Please help.
Is there like a specific difference I'm suppose to find?
I'm super confused.

  • math -

    x grows by 2
    the slope is 2, so y grows by 4.

    so, y=2+4=6

    or, more formally,

    (y-2)/(3-1) = 2
