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

Ordered pair that has a positive x-coordinate and a positive y-coordinate would be plotted in which quadrant?
quadrant one
Is the y coordinate of a point in quadrant II is negative?
in 2nd quad y coordinate is positive
What must be true about the coordinates of any point that lies in the second quadrant?
The x coordinate in the second quadrant is negative while the y coordinate is positive.
In which quadrant would an ordered pair that has a negative x-coordinate and a positive y-coordinate be plotted?
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.
What is minimum point?
This is the coordinate of the vertex for a parabola that opens up, defined by a positive value of x^2.
What is the quadrant of a ordered pair that has a negative x coordinate and a positive y coordinate?
An ordered pair that has a negative x-coordinate and a positive y-coordinate (-,+) would be plotted in which quadrant?
Ordered pair that has a positive 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 which quadrant Remember to use Roman Numerals to write the quadrant numbers?
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.
Is y coordinate always a negative number?
No, the y-coordinate can be positive or negative.
In which quadrant is the x coordinate negative and the y coordinate positive?
Second quadrant (II).
A point that has a negative x-coordinate and a positive y-coordinate is located in which quadrant?
2
Is the y coordinate of a point in quadrant II is negative?
in 2nd quad y coordinate is positive
A coordinate grid that shows both positive and negative numbers is sometimes called a?
Coordinate plane
Two lines with positive slopes are parallel?
It depends if they have the same positive slope if yes then they are parallel.
A point that has a positive x-coordinate and a negative y-coordinate is located in which quadrant?
quadrent IV(4)
What does x-coordinate mean?
In a coordinate system, it represents the distance from the origin in the positive direction of the x-axis.
Can two lines with positive slopes be parallel?
yes they can be parallel because for a pair of lines to be parallel the slope must be the same no matter if the slope is positive or negative.
