    I’m really struggling with some of these questions...
    (if there are images there then I cant see them so I'm sorry.)
    2 quick facts that can help: perp lines gradients times to make -1.
    horizontal lines grad = 0
    vertical lines grad = undefined

    when finding the equation of a line, you should use:
    y-b=m(x-a) where a and be are the x and y of a point on the line (a,b)
    and m = gradient.

    to find gradient its y1-y2/x1-x2.

    thats all you need to know really, unless its exponential or something else.
    edit: welp, just saw now you made another post with the images. I'll look at it and give you hints.

    You have the length of AC, you should know how to get it.
    for the angle at A use: m=tan(theta)
    so: 2/3 = tan(theta)
    the angle = tan-1 (2/3)

    ask if you need more help.
