Homework Statement
For the line y=2x+4
A, find the posiotion vector of the point A, on the line, Which is 6 units from the origin in the 1st quadrant. Express your answer in:
i.] Matrix form. [Never done matrix]
ii.] the form OA [Line with arrow pointing right above it.] = xi +yj
B, Find the position vector for the point B on the line, which is 12 units from the origin in the 3rd quadrant. Express your answer in,
i.] Matrix
ii.] the form OB [Line above it facing right.]
C, Find the cordinates of the mid point of AB.
d, what is the vector equation of the line y=2x+4 in parametric form?
The Attempt at a Solution
Now I know I am nearly 19. Finished school 2 years ago and am now working a 5am-5pm job manuel not pen pushing an just find it hard to study and remeber when I am working.
So forgive me for F%%$ing up.
Right apart from just drawing the graph of y=2x+4 that is all I get.
I think they are meaning to add a point 6 units from the 0 middle point on graph. But not sure.
Which would give me a rectangle. Point starting from -2,0 0,6 14,6. That is if I have done it right. I have done it x,y. That they right way around.
What on Earth do I do from here if I am right?
Cheers,
mac
