Slope
|
The slope of the line is a # that measures steepness.
EX: M=? |
|
|
Slope formula
|
The m of the line through the
points (x1, y1) and (x 2, y 2). ex: M= y2-y1 / x2-x1 |
|
|
x-intercept
|
Point at which the line crosses the x-intercept. you replace y with 0.
EX:3x + 4( 0 ) = 12 3x + 0 = 12 3x = 12 x = 12/3 x = 4<-----x-intercept |
|
|
y-intercept
|
Point at which the line crosses the y-intercept. you replace x with a 0.
EX: 25x2 + 4y2 = 9 25(0)2 + 4y2 = 9 0 + 4y2 = 9 y2 = 9/4 y = ± ( 3/2 )<---y-intercept |
|
|
Horizontal line
|
The line parallel to the x-axis.
EX: x = 5 |
