    \[\huge~\rm~y-y_1=m(x-x_1)\] Use this it is the Point-slope formula Substitute the follwing values into the formula m=slope so 3 4=x1 7=y1 (x1,y1)

    y-7=3(x-4) is that all?

    Do they want slope -intercept form?

    it just says write an equation, it doesn't specify what type.

    So slope intercept form.... y-7=3(x-4) \[\huge~\rm3(x-4) \] distribute that
