in the xy plane , what is the y intercept of line L?
A) Slope = 3 times the y intercept
B) X intercept = -1/3
A) Slope = 3 times the y intercept
B) X intercept = -1/3
for equation of line Y = mx + c
A states m = 3c. Y= 3cx + c hence not sufficient. there will be mutliple lines that satisfy this condition each with a different Y intercept.
B states X intercept = -1/3. we know nothing about the slope so insufficient.
Together A + B: there will atleast be 2 lines one with +ve slopw and other with -ve slope that cuts x-axis at -1/3 whose slope is 3 times the Y-intercept.
hence insufficient. ANs: E
