A line has yintercept (0, 3) and is perpendicular to the line 2x + y = 3. Find the xintercept of the line.

since the given line has slope 2, we want slope 1/2.
So, y = x/2 + b
Since when x=0, y=3, b=3 and
y = x/2 + 3
So, when y=0, x=? 
So would the answer be 6 or 3 then

Neither, it would be 6
taking Steve's equation of y= x/2 + 3 , and letting y = 0
0 = x/2 + 3
3 = x/2
6 = x
