C1: Slope
- Slope of a line
- Slope= rise/run
- the slope of a line segment on a
coordinate grid is the measure of its rate
of change: rate of change= change in
y/change in x
- count the units to determine the rise and run of a slope
- Vocab
- rise
- the vertical distance between 2 points
- run
- the horizontal distance between 2 points
- rate of change
- the change in one
quantity with respect
to the change in
another quantity
- slope
- a measure of how one quantity changes
with respect to the other it can be
determined by calculating rise/run
- negative reciprocals
- two numbers whose product equals -1
- types of lines and their value
- lines sloping down to the left
- have a negative slope
- lines sloping up to the right
- has a positive slope
- horizontal lines
- slope=0
- vertical lines
- slope is undefined
- parallel lines
- parallel lines have an
equal slope to each
other
- perpendicular lines
- if you multiply the slopes of two
perpendicular lines it will equal -1
because they are negative reciprocals
of each other
- using slope to id a polygon
- *to check whether a polygon is a
rectangle determine whether two of the
intersecting sides are perpendicular
(slopes should be negative reciprocals)
- equations used to find slope
- y=mx+b
- rise/run
- rate of change= change in y/change in x
- y2-y1/x2-x1
