1st Semester Exam Review - SREB (Part 1)

Front

What is the definition of Slope?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line (y = mx + b). It is calculated as the rise over run, or the change in y divided by the change in x.

Front

What does Ratio mean in mathematics?

Back

A ratio is a relationship between two numbers indicating how many times the first number contains the second. It is often expressed as 'a:b'.

Front

How do you calculate Miles in a distance problem?

Back

Miles can be calculated using the formula: Distance = Speed × Time. Ensure that speed is in miles per hour and time is in hours.

Front

What does 'How Long?' refer to in problem-solving?

Back

'How Long?' typically refers to the duration of time required to complete a task or travel a distance, often calculated using time = distance/speed.

Front

What does it mean to Simplify an expression?

Back

To simplify an expression means to reduce it to its simplest form by combining like terms, eliminating parentheses, and performing operations.

Front

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

Back

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

Front

What is a Proportion?

Back

A proportion is an equation that states that two ratios are equal. For example, a/b = c/d.

Front

What is the difference between Distance and Displacement?

Back

Distance is the total path length traveled, while displacement is the shortest distance from the initial to the final position, including direction.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

How do you convert a fraction to a decimal?

Back

To convert a fraction to a decimal, divide the numerator by the denominator.
