(1) A line with a negative slope declines from left to right, and thus will always intersect the 2nd quadrant - assuming that the line is infinite in b oth directions, there's just no way to draw it so that it doesn't intersect the 2nd quadrant at SOME point. Stat. (1) is sufficient.prachich1987 wrote:Does line k intersect quadrant II?
a. Slope of k is -1/6
b. Y intercept of k is -6
(2) ALONE, this tells you nothing about the line, except that it intersects y axis at point -6. If the line's slope is negative, it will hit 2nd quad at some point; if the line's slope is positive (rising from left to right) or zero (horizontal, parallel to x axis) it will never his 2nd quad. Insufficient
Answer is A.
