(Assignment) X intercept and Y intercept

Front

What is the x-intercept?

Back

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

Front

What is the y-intercept?

Back

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

Front

True or False: The x-intercept of a function ALWAYS occurs where y is equal to zero.

Back

True

Front

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

Back

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

Front

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

Back

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

Front

What are the coordinates of the x-intercept in the equation y = 2x - 6?

Back

(3, 0) because setting y to 0 gives 2x - 6 = 0, thus x = 3.

Front

What are the coordinates of the y-intercept in the equation y = 2x - 6?

Back

(0, -6) because setting x to 0 gives y = -6.

Front

In the graph of a function, what does the point (0, b) represent?

Back

It represents the y-intercept of the function.

Front

In the graph of a function, what does the point (a, 0) represent?

Back

It represents the x-intercept of the function.

Front

If a line has an x-intercept of 4, what is the value of y at that point?

Back

0, because the x-intercept occurs where y is zero.
