Given the point A(1,20 and the slope 1/2 write the equation of the line.

This problem requires the point slope
formula:


y - y1 = m(x - x1), where x1 and y1 are the
coordinates of the given point A and m is the slope of the
line.


We'll consider x1 = 1 and y1 = 2
(since the 0 key has the brackets symbol on it, we'll consider 0
as being an error of typing)
. The slope is m =
1/2.


y - 2 = (1/2)*(x -
1)


We'll remove the
brackets:


y - 2 = x/2 - 1/2


y
= x/2 + 2 - 1/2


y = x/2 +
3/2


The requested equation of the line, whose
slope is m = 1/2 and it's passing through the point A(1,2), is: y = x/2 +
3/2.

What accomplishments did Bill Clinton have as president?

Of course, Bill Clinton's presidency will be most clearly remembered for the fact that he was only the second president ever...
