Math notes zach
Ax +by=c • X CANT BE NEGATIVE
X AND Y INTERCEPT • TO FIND X CHANGE Y TO 0 • TO IFND Y CHANGE X TO 0
SLOPE • CHANGE IN Y- PLUS GOES UP MINUS GOES DOWN • CHANGE IN X PLUS GOES RIGHT MINUS GOES LEFT
SLOPE FORMULA • M=Y2-Y1 OVER X2-X1
LINEAR EQUATIONS • VARIABLES HAVE NO EXPONENTS GREATER THAN 1 • VARIABLES CANT BE MULTIPLIED TOGETHER • VARIABLES CANNOT BE IN DENOMINATER • VARIABLE CANT BE UNDER RADICALS
