Ответ:
option 2 : y-7 = 2(x-1)
Step-by-step explanation:
the fastest way is to simply put the x- and y-values of both points into the equations, and see, which one is true for both points.
the first option is only true for the second point
7-7 = 4(1-1)
0 = 4×0 = 0
but for the first point
3-7 = 4(-1 - 1)
-4 = 4×-2 = -8
-4 = -8 is false
the second option then is true for both points
7-7 = 2(1-1)
0 = 0
3-7 = 2(-1 - 1)
-4 = 2×-2 = -4
