You can put this solution on YOUR website!
(3,5),
(3,8) m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29 = -3/0 undefined
.......
0.5x-0.2y=1.2
the standard slope-intercept form for an equation of a line is
y+=+highlight_green%28m%29x+%2B+highlight%28b%29 where m is the slope and b the y-intercept.
y = (.5/.2)x - 1.5/.5
m = 5/2
