8th Grade Math Review Quarter 2

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing an equals sign (e.g., 15k - 2 = 28).

Front

What is the Y-axis?

Back

The Y-axis is the vertical axis in a coordinate plane, used to represent the dependent variable in a graph.

Front

What can be said about the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

How do you find the slope of a line given two points?

Back

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

Front

What is the equation of a vertical line?

Back

The equation of a vertical line is in the form x = a, where 'a' is a constant.

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

The slope is 2.

Front

What does the term 'slope' refer to in mathematics?

Back

Slope refers to the steepness or incline of a line, calculated as the rise over run.

Front

What is the difference between an expression and an equation?

Back

An expression does not contain an equals sign, while an equation does.

Front

What is the X-axis?

Back

The X-axis is the horizontal axis in a coordinate plane, used to represent the independent variable in a graph.

Front

What is the formula for the slope-intercept form of a line?

Back

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