In the xy-plane, if line k has negative slope and passes through the point (-5, r), is the x-intercept of line k positive?
1) slope of line k is -5
2) r > 0
oa-E
Many slope problems are best solved by DRAWING.
Statement 1: Slope = -5
Statement 2: When x = -5, r > 0
Both statements are satisfied by the following cases:
Case 1:
Here, the x-intercept is negative.
Case 2:
Here, the x-intercept is positive.
Thus, the two statements combined are INSUFFICIENT.
The correct answer is
E.
