C2-3: Equations of Linear Functions
- equations
- slope intercept
- y=mx+b
- y=mx+b
- point slope
- y-y=m(x-x)
- y-y=m(x-x)
- vertical
- x=a (x intercept)
- y=-c/a (general)
- x=a (x intercept)
- horizontal
- y=b (y intercept)
- y= - c/b
- y=b (y intercept)
- slope
- rise/run or y2-y1/x2-x1
- rise/run or y2-y1/x2-x1
- general
- ax+by+c=0
- ax+by+c=0
- standard
- ax+by=c
- ax+by=c
- slope intercept
- vocab
- slope intercept form
- slope point form
- general form
- slope intercept form
- types of lines
- oblique
- slanted lines that will always
intersect both the x and y
axis'
- slanted lines that will always
intersect both the x and y
axis'
- horizontal
- parallel to the x axis and will only
have a y intercept
- parallel to the x axis and will only
have a y intercept
- vertical
- are parallel to the y axis
and only have an x
intercept
- are parallel to the y axis
and only have an x
intercept
- oblique
- Tips
- given the equation of
any straight line we
can determine the x
and y intercepts by
replacing one variable
with 0 and solving the
other
- its common to
express the
equation of a
linear function in
either point slope
or general form
- unlike oblique and
horizontal lines a
vertical line is not a
function
- parallel lines have the
same slope
- perpendicular lines are negative reciprocals
of each othe
- you can use any point on the line
to find the
- given the equation of
