Define - "ordered = (x, y)
pairs" = a single point on a coordinate plane
Define - "origin" = (0,0)
= the point where two axes meet
Explain - "quadrants" = when the two axes (x and y) cross they form 4
quadrants
= "distance" - the length between two points on a
plane - (x1, y1), (x2, y2)
Explain what - "the * does not have to be forming a line
distance" means *distance is ALWAYS positive
Define - "distance
formula" for a line(s) = (Distance (d) =
"square root" all
over - [( x2-x1)^2 +
(y2-y1)^2]
= "midpoint" - the middle point between
two points on a plane - (x1, y1), (x2, y2) -

Explain what - "the that are forming one line
midpoint" means *remember - "MidPOINT"
Define - "midpoint
formula" for a line(s)
= Midpoint (M) = [(x1+x2)/2] , [(y1+y2)/2]
Coordinate Plane = = 2D

= a horizontal or vertical line
= (x=0) - horizontal - (look at the location of (x)
Describe/Define on the coordinate plane)
what a "one = (y=0) - vertical - (look at the location of (y) on
demential (1D) line" the coordinate plane)
is
In a 1D line, what
= Distance and Midpoint:
two things need to
= horizontal = (D = ("absolute value" X2-x1))
be accounted for
and explain how we = (M = (x1+x2)/2)
can do this = vertical = (D = ("absolute value" y2-y1))
= (M = (y1+y2)/2)
Define/Explain - = (m)=(rise/run)=(change in y/change in x)
"slope" of a line = (y2-y1/x2-1)
When looking at a = (-) "negative slope" = (line starts in Q3 - the
graphed line - how line ends in Q1)
