Y-intercept and Slope

Front

What is the y-intercept in a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, representing the value of y when x is 0.

Front

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

Back

To find the y-intercept, set x to 0 in the equation and solve for y.

Front

What is the slope in a linear equation?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, showing an upward trend.

Front

If the slope of a line is 0, what does that mean?

Back

A slope of 0 means the line is horizontal, indicating that y does not change as x changes.

Front

If the slope is undefined, what does that mean?

Back

An undefined slope means the line is vertical, indicating that x does not change as y changes.

Front

What is the y-intercept of the equation y=5?

Back

The y-intercept is 5, as the line is horizontal and intersects the y-axis at y=5.

Front

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

Back

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