Back

0

Front

What does the x-intercept represent in a graph?

Back

The point where the graph crosses the x-axis (y=0).

Front

What does the y-intercept represent in a graph?

Back

The point where the graph crosses the y-axis (x=0).

Front

How do you find the x-intercept of an equation?

Back

Set y=0 and solve for x.

Front

How do you find the y-intercept of an equation?

Back

Set x=0 and solve for y.

Front

What is the slope-intercept form of a line?

Back

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

Front

What is the relationship between the slope and the x-intercept?

Back

The slope indicates the steepness of the line, affecting how quickly it rises or falls as x changes.

Front

What is the significance of the coefficients A and B in the standard form Ax + By = C?

Back

A and B determine the slope of the line when rearranged into slope-intercept form.
