| slope y-intercept | y=mx+b
🗑
|

| standard form | Ax+By+C=0
🗑
|

| slope equation | y2-y1/x2-x1 or for a graph rise/run
🗑
|
||||
| fixed number | y-intercept
🗑
|

| variable number/constant multiple/ constant of variation | slope
🗑
|
||||
| m= | slope
🗑
|
||||
| b= | y-intercept
🗑
|
||||
| horizontal lines | slope is zero, slope in equation is y=0x+b, y=b is the equation
🗑
|
||||
| vertical lines | slope doesn't exist=undefined, can't use slope y-intercept for vertical lines, written in the form x=a where a is the x-intercept
🗑
|
||||
| direct variation | passes through the origin (0,0) y=mx
🗑
|
||||
| partial variation | doesn't pass through the origin (0,0) y=mx+b
🗑
|
||||
| linear | points form a straight line, first differences are constant
🗑
|
||||
| non-linear | points don't form a straight line, first differences aren't constant
🗑
|
||||
| linear system | a set of two or more linear equations that are considered simultaneously
🗑
|
||||
| point of intersection | the point where two (or more) lines cross
🗑
|
||||
| two parallel lines | never cross, no common points, no solution
🗑
|
||||
| two non-parallel lines | intersect at one point, one solution
🗑
|
||||
| two identical lines | equation different but same line, infinite number of solutions
🗑
|
||||
| parallel lines | lines which run in the same direction and never cross
🗑
|
||||
| perpendicular lines | lines which intersect at right angles (90o)
🗑
|
||||
| how to know if two equations are parallel | they have equal slopes
🗑
|
||||
| how to know if two equations are parallel | the slopes are negative reciprocals
🗑
|
||||
| x-intercept | the value of x where the line crosses the x-axis (y=0)
🗑
|
||||
| y-intercept | the value of y where the line crosses the y-axis (x=0)

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
