assuming a constant driving speed, the time required for a car trip increases as the distance of
the trip increases. Is this direct or inverse?
DIRECTLY PROPORTIONAL
inverse proportion
AN INCREASE IN 1 QUANTITY IS ACCOMPANIED BY A DECREASE IN THE OTHER
- Or vice versa
the time required for a car trip decreases as the speed increases and increases as the speed
decreases. Is this direct or inverse?
INVERSE PROPORTION
ratio
, A COMPARISON OF 2 QUANTITIES IN A PARTICULAR ORDER
- Reduced to their smallest whole number
constant of proportionality
2 QUANTITIES HAVE A PROPORTIONAL RELATIONSHIP SO THIS EXISTS B/W THE

THE PRODUCT OF A REAL NUMBER
- Also called a coefficient

single variable linear expression
THE SUM OF A SINGLE VARIABLE TERM WHERE THE VARIABLE HAS NO EXPONENT
AND A CONSTANT WHICH MAY BE 0
EX: 2w + 7 has 2w as the variable term and 7 as the constant term
linear expression
THE SUM OF ANY NUMBER OF VARIABLE TERMS SO LONG AS NONE OF THE
VARIABLES HAVE AN EXPONENT
EX: 3m + 8n - 1/4p + 5.5q - 1 is a correct expression
