First rearrange the second equation to fit the form y = mx + c, where m = slope
We get y = (9/k) x - 7/k
Parallel lines have the same slope. From equation 1, slope = k
From equation 2, slope = 9/k . Equating the two slopes we get k = 9/k; k² = 9; k = 3
quadrant one
in 2nd quad y coordinate is positive
The x coordinate in the second quadrant is negative while the y coordinate is positive.
The quadrants formed by the x and y axes are numbered anticlockwise from the quadrant in which both coordinates are positive (which is quadrant I). Thus negative x and positive y is in the quadrant II.
Any two lines, if their slops are equal, are either parallel or else the same line.
An ordered pair that has a negative x-coordinate and a positive y-coordinate (-,+) would be plotted in which quadrant?
quadrant one
An ordered pair that has a negative x-coordinate and a positive y-coordinate would be plotted in the second quadrant (II). In this quadrant, the x-coordinate is negative and the y-coordinate is positive.
No, the y-coordinate can be positive or negative.
Counterclockwise rotation is considered positive based on the standard convention used in mathematics, particularly in trigonometry and coordinate geometry. This convention aligns with the orientation of the Cartesian coordinate system, where angles are measured from the positive x-axis. Clockwise rotation, on the other hand, is deemed negative as it moves in the opposite direction. This differentiation helps maintain consistency in mathematical equations and calculations involving angles.

Second quadrant (II).
It depends if they have the same positive slope if yes then they are parallel.

quadrent IV(4)
In a coordinate system, it represents the distance from the origin in the positive direction of the x-axis.
