Models and Relationships
Slope
Describes the direction and the steepness
of the line.
The line is constant. Its always linear.
X and Y axis
X axis is sideways (horizontal line)
Y axis is up (vertical line)
X is always first when
naming a coordinate. (x,y)
Independent and Dependent Variables
Y axis is dependent on X axis
because its independent.
Used to graph linear equations
Ratios
A ratio compares values.
It says how much of one thing
there is compared to another thing.
Quadrants on a cartesian plane
The quadrant numbers
goes counter clockwise
They identify positive or negative
coordinates on the plane.
Formulas
y = mx + b
Tables of values
these are used to record data and
then analyze them to find a pattern
to be able to make predictions
m = rise/run
y2 - y1
_____
x2 - x1
Left side coordinate is always
the first (x1,y1) then, (x2,y2) on
the next coordinate
Used to find the equation of a line in a graph
