Linear Vocabulary Review RC1

Front

What are zeros in algebra?

Back

Zeros are the x-values where a function equals zero or a graph crosses the x-axis.

Zeros are written x = #.

Front

What is an x-intercept?

Back

An x-intercept is the point where a graph crosses the x-axis. It occurs when the y-value is zero.

Written as (#, 0)

Front

What is slope in algebra?

Back

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

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis. It occurs when the x-value is zero.

Front

What does rate of change mean in algebra?

Back

Rate of change refers to how one quantity changes in relation to another. In linear equations, it is represented by the slope.

Front

What do inequality symbols represent?

Back

Inequality symbols (e.g., <, >, ≤, ≥) represent the relationship between two values, indicating whether one is less than, greater than, or equal to the other.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations in the system.

Front

Difference between an equation and inequality.

Back

Equations are two expressions set equal (=) to each other.

Inequalities have inequality symbols instead. (<, >, ≤, ≥)

Front

How do you graph a linear equation?

Back

Begin with b & move like m.
Plot the y-intercept (b), use the slope (m) to rise and run to find another point.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts. Parallel lines never intersect.
