Idk if I'm being stupid but this question is really confusing me.
1. Draw the line y=2x+3. Find the equation obtained when the line is translated through (4 1) (vector btw)
i. by a graphical method.

I drew the graph but how to I translate it through (4 1)

One way would be to pick a couple of points on the line, and translate each of them by (4,1). Then draw the new line through the two new points, and you're done.

You can choose any points, but probably easiest to choose where the original line crosses each of the axes.
