Finding X and Y Intercepts Flashcard

Front

What is the definition of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, which occurs when x = 0.

Front

How do you find the y-intercept of a linear equation in standard form (Ax + By = C)?

Back

To find the y-intercept, set x = 0 and solve for y.

What is the general form of a linear equation?

Back

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

Front

What does the slope of a line represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

How can you determine the slope from two points on a line?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

How can you graph a linear equation using its intercepts?

Back

To graph a linear equation using its intercepts, plot the x-intercept and y-intercept on the coordinate plane and draw a line through these points.
