MATH 8 SEMESTER 2 FINAL 2024-2025

Front

What is the Pythagorean Theorem?

Back

In a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².

Front

How do you find the slope of a line?

Back

The slope (m) is calculated as the change in y divided by the change in x (rise over run). Formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations.

Front

What does it mean to reflect a point over the x-axis?

Back

Reflecting a point (x, y) over the x-axis results in the point (x, -y).

Front

What is the solution to the equation 4x + 6 = 18 + 2x?

Back

x = 6.

Front

What is the solution to the equation -2x - 3 = 3x + 2?

Back

x = -1.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle is given by the formula A = 1/2 * base * height.

Front

What is the distance formula?

Back

The distance (d) between two points (x1, y1) and (x2, y2) is given by d = √((x2 - x1)² + (y2 - y1)²).
