Question 1156124
<br>
1.  The equation is x=2 <br>

{{{ drawing(400,400, -5,5,-5,5, grid(1), green(line(2,-5,2,5))
) }}}<br><br>


2.  y - y0 = m(x - x0)   (m = slope, (x0,y0) = point through which the line passes)

    y - 3 =  (4/7)(x - (-2))
    y - 3 =  (4/7)(x + 2)
    y - 3 = (4/7)x + 8/7
    y = (4/7)x + 8/7 + 3
{{{highlight(    y = (4/7)x + 29/7 ) }}}
