Question

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

Answer 1

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=?

Answer 2

So would the answer be 6 or 3 then

Answer 3

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
