Identifying Y-intercept(Graphs)

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It represents the value of y when x is 0.

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept from a graph, look for the point where the line intersects the y-axis.

Front

What does a positive y-intercept indicate?

Back

A positive y-intercept indicates that the value of y is positive when x is 0.

Front

What does a negative y-intercept indicate?

Back

A negative y-intercept indicates that the value of y is negative when x is 0.

Front

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

Back

It means that when x is 0, the value of y is 4.

Front

What is the significance of the y-intercept in real-life scenarios?

Back

The y-intercept can represent initial values in real-life situations, such as starting amounts or initial conditions.

Front

In the equation y = mx + b, what does b represent?

Back

In the equation y = mx + b, b represents the y-intercept.

Front

How can you determine the y-intercept from an equation?

Back

To determine the y-intercept from an equation, set x to 0 and solve for y.

Front

What is the y-intercept of the equation y = 2x - 6?

Back

The y-intercept is -6, found by setting x to 0: y = 2(0) - 6.

Front

What is the y-intercept of the equation y = -3x + 4?

Back

The y-intercept is 4, found by setting x to 0: y = -3(0) + 4.
