Lines and Slopes
100
In this quadrant of the coordinate plane, x is positive and y is negative.
What is the IV quadrant?
100
This is a point on the y-axis that has a x value always equal to zero.
What is a y-intercept?
100
This is a shown by m and calculated by rise/run.
What is slope?
200
This a point on a graph that is not within any quadrant and is often denoted by (0,0).
What is the origin?
200
This is a graph with a point that is both point (x, y) and point (x, -y).
What is x-axis symmetry?
200
A line on a graph has a undefined slope.
300
This is called the distance formula and shows the distance between (x1, y1) and (x2, y2).
What is
300
If a graph has a point (x, y) but does not contain any reflected points.
What is no symmetry?
300
A line on a graph has a undefined slope.
What is a vertical line?
400
This is the halfway point between (x1, y1) and (x2, y2). It is often called half the distance. It is denoted by
What is the midpoint formula?
400
If a graph has points on (5, 6), (-5, 6), (5, -6), and (-5, -6) it contains symmetry.
What is x-axis, y-axis, and origin symmetry?
400
This line has a slope of zero and is a straight line.
What is a horizontal line?
