G - Chapter 4 Test Morning Work

Front

What is the equation of a line with a slope of 4 and a y-intercept of 2?

Back

y = 4x + 2

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the line, indicating how much the y-value changes for a unit change in the x-value.

Front

What is the slope of line segment AC if the coordinates are (x1, y1) and (x2, y2)?

Back

The slope is calculated as \( m = \frac{{y2 - y1}}{{x2 - x1}} \).

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If the slope of a line is 3, what does this mean in terms of rise over run?

Back

For every 3 units the line rises, it runs 1 unit horizontally.

Front

What is the slope of the line represented by the equation y = 2x + 5?

Back

The slope is 2.

Front

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

Back

Use the formula \( m = \frac{{y2 - y1}}{{x2 - x1}} \).

Front

What is the slope of the line represented by the equation y = -4x + 1?

Back

The slope is -4.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.
