🟣Friday - Extra Credit 1 - x-intercepts and y-intercepts

Front

What is the y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis. It is represented as (0, y).

Front

What is the x-intercept?

Back

The x-intercept is the point where a graph crosses the x-axis. It is represented as (x, 0).

Front

How do you find the y-intercept from a linear equation?

Back

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

Front

How do you find the x-intercept from a linear equation?

Back

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

Front

What is the significance of intercepts in graphing?

Back

Intercepts help identify key points on the graph and are useful for sketching the graph of a function.

Front

If a line has a y-intercept of -1, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -1).

Front

If a line has an x-intercept of (2, 0), what does this indicate?

Back

It indicates that the line crosses the x-axis at the point (2, 0).

Front

What are the coordinates of the y-intercept if the equation is y = 2x + 3?

Back

The y-intercept is (0, 3).

Front

What are the coordinates of the x-intercept if the equation is y = -x + 4?

Back

The x-intercept is (4, 0).

Front

How can you determine both intercepts from the equation y = mx + b?

Back

The y-intercept is b (0, b) and the x-intercept can be found by setting y = 0 and solving for x.
