slope
|
is also know as m describes the line and function. it can be horizontal or vertical pending.it also know as rise over run when being graphed. used in slope intercept form.
|
|
|
Slope intercept form
|
is presented as y=mx+b it shows where the y-intercept is on the graph which is b in the formula.It is used for linear equations. m is the slope.
|
|
|
Horizontal line
|
parallel to the x axis and goes right through the y- axis on the graph. and has no x-intercept only a y-intercept. An example how it would be written :
y=2 or y=7 |
|
|
Point-Slope form
|
a way to wright an equation of a line. the formula is written as m=y2-y1/x2-x1and then you wright as y-y1=m(x-x1) also a different way of writing slope.
|
|
|
x-intercept
|
The x-intercepts is when the line crosses the graph of x-axis.x-intercept is a point on the graph where y=0
|
|
|
Standard form
|
(Ax + By = C) is a form of a linear equation.A,B,C are integers. and A> or equal to 0.
|
|
|
Vertical line
|
the vertical line is the opposite of a horizontal line. it is x=y when graphed other than y=x. and only has an x-intercept.
|
|
|
Slope Formula
|
The slope m of the line through the
points (x1, y1) and (x 2, y 2) is given by the formula. |
|
|
y-intercept
|
it is located on the y-axis on the graph where the line would hit. it is also described as the letter b in slope intercept form.
