TI 84 Scavenger Hut (Algebra)

What is the difference between a rational number and an irrational number?

• A rational number can be expressed as a fraction, while an irrational number cannot be expressed as a simple fraction.

• Both rational and irrational numbers can be expressed as fractions.

• Rational numbers are always whole numbers, while irrational numbers are decimals.

• Irrational numbers can be expressed as fractions, while rational numbers cannot.

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

• Slope (m) = (y2 - y1) / (x2 - x1).

• Slope (m) = (x2 - x1) / (y2 - y1).

• Slope (m) = (y1 + y2) / (x1 + x2).

• Slope (m) = (y2 + y1) / (x2 - x1).
