In the xy-plane, the line with equation ax + by + c = 0, where abc ≠ 0, has slope 2/3 . What is the value of b?
(1) a = 4
(2) c = −6
(1) a = 4
(2) c = −6
ax+by+ c = 0 can be written as y=(-a/b)x -(c/b)
equation for a line is y = mx +c where m is the slope and c is the constant
Thus implying slope = m = 2/3 = -a/b
According to statement 1, if a = 4
2/3 = -4/b => b = -6
statement 2 is in INSUFF because it does not give us anything to work with to get a or b.
So IMO A
Whats the OA?
