x and y intercepts

Front

What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, meaning the y-coordinate is zero.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the x-coordinate is zero.

Given the ordered pair (9,0), what does it represent?

Back

It represents the x-intercept of the graph.

Front

Given the ordered pair (0,4), what does it represent?

Back

It represents the y-intercept of the graph.

Front

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

Back

Set y = 0 in the equation and solve for x.

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

Back

Set x = 0 in the equation and solve for y.

Front

What is the significance of the x-intercept in a real-world context?

Back

It can represent a point where a quantity reaches zero, such as time when a project starts.

Front

What is the significance of the y-intercept in a real-world context?

Back

It can represent the initial value of a quantity before any changes occur.

Front

If a line has an x-intercept of 4, what does this mean?

Back

The line crosses the x-axis at the point (4,0).

Front

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

Back

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