what are integers and rational numbers? how are points graphed
on a coordinate plane?

Integers: a number that can be written without a fractional component

Rational Numbers:  is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number

Step-by-step explanation:

How are points graphed

on a coordinate plane?

Start at (0, 0), or the origin.

Move over x units to the right or left.

Move over y units up or down.

Mark the point.

idk

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
