Hi
Need to sketch graphs
2x+7 Blue   a = 2
2x-3 Green  (Green and Blue //)
-.5x + 7    b = -1/2 (Perpendicular to the Above)
2x-3 = -.5x + 7,   x = 4  and y = 5,  (4,5) & (0,7) points of intersection
(0,7)
(4,5) sqrt(16 +4) = sqrt(20), perpendicular distance between the pair of parallel lines.
{{{drawing(300,300,  -10,10,-10,10,   grid(1), 
circle(0, 7,0.4),
circle(4, 5,0.4),
graph( 300, 300, -10,10,-10,10,   0, 2x+7, 2x-3, -.5x + 7) )}}}
