Answer:
⊕ y=2x+4
Step-by-step explanation:
1) all the answers are provided in slope-interception form, then
2) the slope of the required line is: (12-8)/(4-2)=2. The required line is like to y=2x+??;
3) if the points (2;8) and (4;12) belong to the line required, then the point (0;4) also belongs to this one. It means, the interception is 4;
4) finally, the line required is y=2x+4.
PS. note, the suggested solution is not the only way.
