End of Year- Math 8 Review

Front

Find the slope between the points (-3, 3) and (7, 6).

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1) = (6 - 3) / (7 - (-3)) = 3/10.

Front

What is the sum of the interior angles of a triangle?

Back

The interior angles of a triangle add up to 180 degrees.

Front

What is the value of 7⁰?

Back

7⁰ = 1.

Front

What type of transformation is represented by the change from triangle ABC to triangle A'B'C'?

Back

The transformation is a reflection across the x-axis.

Front

Which equation represents a line with a slope of -2/3 and a y-intercept of 5?

Back

The equation is y = -2/3x + 5.

Front

Define slope in the context of a linear equation.

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the rise (change in y) over the run (change in x).

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.
