Pre-Alg 4.1-4.2 Retake Assignment

Front

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

Back

The y-intercept is the value of y when x is 0, representing the starting point of the line on the y-axis.

Front

How do you identify the y-intercept from the equation y = mx + b?

Back

The y-intercept is the value of b in the equation, which is the point where the line crosses the y-axis.

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How can you find the y-intercept from a table of values?

Back

Look for the row where x = 0; the corresponding y value is the y-intercept.

Front

What is the y-intercept of the equation y = 3x + 9?

Back

The y-intercept is 9.

Front

What is the y-intercept of the equation y = 4x - 12?

Back

The y-intercept is -12.

Front

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

Back

The y-intercept is 0.

Front

How do you graph a linear equation using the y-intercept?

Back

Start by plotting the y-intercept on the y-axis, then use the slope to find another point.

Front

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

Back

It often represents a starting value or fixed cost in various contexts, such as business or physics.

Front

How can you determine the y-intercept from a graph?

Back

Identify the point where the line crosses the y-axis; this point's coordinates give the y-intercept.
