FLASHCARD QUESTION

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

2.

FLASHCARD QUESTION

Front

What does it mean if a system of equations has 0 solutions?

Back

It means that the lines represented by the equations are parallel and will never intersect.

3.

FLASHCARD QUESTION

Front

What does it mean if a system of equations has infinite solutions?

Back

It means that the equations represent the same line, so every point on the line is a solution.

4.

FLASHCARD QUESTION

Front

What are the steps for graphing a line?

Back

1. Plot the y-intercept. 2. Use the slope to find a second point. 3. Draw the line through the points.

5.

FLASHCARD QUESTION

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

6.

FLASHCARD QUESTION

Front

What is the y-intercept of the equation y = 4x + 2?

Back

The y-intercept is 2, which is the point where the line crosses the y-axis.

7.

FLASHCARD QUESTION

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.
