    Finding the coordinate of P?

    Can you confirm that this is correct? Alright so I found out the slope of line l is y= 2x - 2. They are asking for what is the coordinate of point P. Well do I just plug in a 0 for y in that equation and solve it?
    y = 2x - 2
    0 = 2x - 2
    2 = 2x
    x = 1

    So the point should be (1,0) Or did I do something wrong? Because the way the graph looks, I don't think x-coordinate 1 is that far on the right.

    Yes, that's it,

    the axes are not drawn to scale so the lines do not "look like" they have a slope of 2, but if they are parallel, then their slopes are 2.

    When x=0, line cosses the y axis, when y=0, line crosses x axis
