Unit 2 Test Review

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run. In this case, the slope is -3/2.

Front

Standard Form is_____________

Back

Standard Form is represented as Ax + By = C, where A, B, and C are integers.

Front

Write the equation into slope-intercept form: y = 3x - 2

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The equation is y = 3x + 1.

Front

Slope intercept form is_______

Back

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

Front

What is the slope and y-intercept of the equation y = 2x - 3?

Back

Slope: 2, Y-intercept: -3.

Front

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

Back

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

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

Convert the equation y = 4x + 5 to standard form.

Back

The standard form is 4x - y = -5.

Front

What is the significance of the slope in real-world applications?

Back

The slope indicates the rate of change, such as speed in a distance-time graph or cost per item in a pricing model.

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.
