Answer:

D (3, 7)

Step-by-step explanation:

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

where [tex](x_1,y_1)[/tex] is a point on the line and [tex]m[/tex] is the slope

[tex]\implies y-3=2(x-1)[/tex]

[tex]\implies y=2x+1[/tex]

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

when x = 3:  [tex]y=2(3)+1=7[/tex]
