INTEGERS: Whole numbers not in decimals.
Ex: -20, 0, 15
CONSECUTIVE INTEGERS: Integers in counting order.
REMAINDER: The integer left over after dividing a number into another.
Ex: 14/6 = 2 R2
300/70 = 4 R20
If 5w + 3v = 13, what is the value of vw ?
(1) w > 0
Statement (1) ALONE is sufficient, but

The equation of a line is in the form
y = mx + b
x, y: variables
b: y intercept
The slope is how steep/flat the line is. It is calculated by y/x, or rise/r
= Rate x Time
= Distance Time
= Distance Rate
sure to convert everything to same
measurements (miles, seconds, etc)
