CO-ORDINATE GEOMETRY

Questão	Responda
CO-ORDINATE GEOMETRY	CH 20
( , )	(x,y)
Midpoint	(add xs , add ys) -------------------- 2
Distance	(x2 -x1)2 + (y2-y1)2
Slope	m=y2-y1 --------- x2-x1
TO CHECK IF A POINT IS ON THE LINE	substitute point into equation: LHS =RHS
SKETCH A LINE WITH 1 POINT AND A SLOPE	rise -------- run
SKETCH THE LINE X+3Y=6	x intercept y intercept
Y=MX+C	m= slope c= y intercept
FIND EQUATION IF GIVEN A POINT AND A SLOPE	y-y1-m(x-x1)
FIND EQUATION GIVEN 2 POINTS	find slope y2-y1 --------- x2-x1 then y-y1-m(x-x1)
PARALLEL LINES PERPENDICULAR LINES	parallel= same perpendicular= turn fraction upside down and change sign
FIND SLOPE IF GIVEN AX+BY+C=0	slope= -no. in front of x ------------------------- no. in front of y
