Front

What is the algebraic equation for the line represented by the table?

Back

y = x - 3

Front

Write the equation of the line that is represented in this table.

Back

y = 2x + 4

Front

Which equation matches the graph? (Click me to see the image)

Front

What is the point of intersection for the red and blue lines?

Back

(1,3)

Front

What is the equation for this graph?

Back

y = -⅔ x + 3

Front

Define the slope of a line.

Back

The slope of a line is a measure of its steepness, calculated as the rise over run between two points on the line.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you find the slope from 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

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What is the difference between a positive and negative slope?

Back

A positive slope indicates that the line rises from left to right, while a negative slope indicates that the line falls from left to right.
