Find x and y intercepts

Front

What is the y-intercept of an equation?

Back

The y-intercept is the point where the graph of an equation crosses the y-axis, represented as (0, y).

Front

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

Back

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

Given the equation 4x + 2y = -12, what is the y-intercept?

Back

The y-intercept is -6.

Front

Given the equation 4x - 10y = 20, what are the x and y intercepts?

Back

x-int = 5, y-int = -2.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept indicates the value of y when x is zero, showing where the line starts on the y-axis.

Front

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

Back

False.

Front

What does the point (0, 5) represent in a graph?

Back

It represents the y-intercept of the equation, where the line crosses the y-axis.

Front

How can you verify the x-intercept of an equation graphically?

Back

By checking where the graph intersects the x-axis.
