Co-ordinate Geometry
What is co-ordinate geometry?
Line/Line segment
points on the plane
ray
x and y
distance between 2 points
Pythagoras derivation
Formula
What happens when you square a square root?
Midpoint
x1+x2/2,y1+y2/2
Line notation
two endpoints of a line segment
Slope
m= y2-y1/x2-x1
/ - slope
Rise over run
Graphing Lines
origin
verifiying a point on a line
parallel lines to axis
Parallel/Perpendicular Lines
Same if parallel
Perpendicular when both slops multiplied give -1
if fraction flip it and change sign
Equation of the line
when given point and slope
when given both points on the line
Rates of change
Distance / Time graphs
slope for speed
y=mx+c
y-intercept
Slope from equation
intersection of two lines
Simultaneous equations
