Answer:

D (3, 7)

Explanation:

Use linear equation formula in point-slope form:
y-y_1=m(x-x_1)

where
(x_1,y_1) is a point on the line and
m is the slope


\implies y-3=2(x-1)


\implies y=2x+1

Inputting the values of the point options in the above equation for the line implies that D is the answer since:

when x = 3:
y=2(3)+1=7
