The Distance Formula
it is used to find the distance between twopoints on the coordinate plane
Pythagorean Theorem can be used to findthe distance between two points.
The Pythagorean theorem is attributed toGreek mathematician PYTHAGORAS OFSAMOS
Midpoint Formula
the midpoint of a segment is a point thatdivides the segment into two congruentsegments
to find the midpoint of a line, simply findthe x and y coordinates of the midpoint
to find the x coordinates
add the first and second value of x anddivide it by two
to find the y coordinates
add the first and second value of y anddivide it by two
Shortest Distance between a point and a line
the shortest distance is the one drawnperpendicular to the line.
Equation of the cirle
In mathematics , CIRCLE is defined as theset of all points equidistant from a fixedpoint called center
The center C is at (h, k), r is the radius andP(x, y) is a point on the circle.
the distance formula is used to find theequation of the circle
thus the equation of the circle whosecenter is at (h, k) and with radius r is
Parallel & Perpendicular Lines
Two lines are parallel if they have the sameslope and different y intercepts
slope of L1 = slope L2
Two lines are perpendicular if their slopesare opposite reciprocals
the product of their slopes is always equalto 1
Graphing Linear Equations
we can graph linear equations using
x and y intercepts
a point and slope of the line
two points of the line
Equation of the Line
linear equations can be written in 3 forms
Standard Form : Ax + By = C
General Form : Ax + By + C = 0
Slope Intercept Form : y = mx + b
