Math 8 Semester 1 Exam

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run. In this case, the slope is 1/2.

Front

What is the meaning of the y-intercept?

Back

The y-intercept is the value of y when x is 0. It represents the starting point of a linear relationship. In this case, it means before sand is put in the bucket, it weighs 1 pound.

Front

What does the slope represent in this situation?

Back

In this context, the slope represents the rate at which the sloth runs, which is 6 feet in 1 minute.

Front

Which of the following BEST describes the transformation?

Back

The transformation is a reflection over the x-axis.

Front

Find h if the equation is given.

Back

h = 35.71.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

Front

What does 'm' represent in the equation of a line?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

What does 'b' represent in the equation of a line?

Back

In the equation y = mx + b, 'b' represents the y-intercept of the line.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula Area = 1/2 * base * height.
