|
|
|
x - axis
|
Horizontal axis
|
|
|
y-axis
|
Vertical Axis
|
|
|
Origin
|
where the axes intersect
|
|
|
Quadrants
|
starting counter clockwise from 1 to 4, the quadrants separate the grid.
|
|
|
Coordinates
|
An ordered pair of number names the location of a point in the plane.
|
|
|
solution
|
an ordered pair (x,y) that makes the equation true.
|
|
|
To find the solution:
|
1. Substitute the ordered pair into the equation and test if they make the equation true.
2. graph the equation to find the solution. |
|
|
slope formula
|
Slope= vertical change/horizontal change which = rise/run
|
|
|
slope intercept form
|
y=mx+b
mx is the slope and b is the y intercept |
|
|
Boundary Line
|
line used to graph an inequality on a plane, either dashed when < or > or solid when <_ or _>
