slope
|
gradient of a line that describes its steepness, incline or grade;As another example, consider a line which runs through the points (4, 15) and (3, 21). Then, the slope of the line is 21-5/3-4=6/-1=-6

|
vertical line
|
A line on the coordinate plane where all points on the line have the same x-coordinate.;(-15,20) and (-15,3)
|

|
standard form
|
simplest terms; Ax+By=C

|
y-intercept
|
The y-intercept is the point where the line crosses the y-axis;example the line crosses the y-axis at point (0,3). Therefore b = 3. The slope is 2.The slope intercept equation is
y = 2x + 3. |
|
|
x-intercept
|
the point where the line crosses the x-axis; To find the x-intercept, set y = 0 and solve for x.
3x + 4( 0 ) = 12 3x + 0 = 12 3x = 12 x = 12/3 x = 4 |
