Day 2 Review: Graphing and Writing Equations!

Front

What is the graph of the equation y = 3?

Back

A horizontal line at y = 3.

Front

What is the y-intercept of a graph?

Back

The point where the graph intersects the y-axis, represented as (0, b).

Front

What does the inequality y > -1/5x - 1/2 represent?

Back

The region above the line y = -1/5x - 1/2.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does the slope of a line indicate?

Back

The steepness and direction of the line; positive slope goes up, negative goes down.

Front

How do you find the y-intercept from the equation 2x - y = 0?

Back

Set x = 0; y = 2, so the y-intercept is (0, 2).

Front

What is the meaning of the term 'inequality' in mathematics?

Back

A relation that shows one quantity is less than or greater than another.

Front

What is the significance of the point (0, 3) on a graph?

Back

It indicates the y-intercept where the line crosses the y-axis.

Front

How do you graph the equation 2x - y = 0?

Back

Rearrange to y = 2x and plot points based on the slope.
