1st Semester Exam Review

Front

What is the result of the expression -1/3 + (-1/6)?

Back

The result is -1/2.

Front

How do you find the slope of a line?

Back

The slope is calculated as the change in y divided by the change in x. If the line is horizontal, the slope is 0.

Front

What is the result of the expression -20 - (-16)?

Back

The result is -4.

Front

What is the result of the expression -6.23 - 7.5?

Back

The result is -13.73.

Front

What is the constant of proportionality (slope) if the slope is 2.5?

Back

The constant of proportionality is 2.5.

Front

Define 'slope' in mathematics.

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change.

Front

What does it mean if a slope is 'undefined'?

Back

An undefined slope occurs in a vertical line where the change in x is 0, making the slope calculation impossible.

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

The formula is m = (y2 - y1) / (x2 - x1).

Front

What is the result of the expression -1/2 + 1/3?

Back

The result is 1/6.

Front

What is the definition of 'constant of proportionality'?

Back

The constant of proportionality is the constant ratio in a proportional relationship, often represented as the slope in a linear equation.
