Intro Slope and Y-Intercept

What is the definition of y-intercept?

• The y-intercept is the point where a line intersects another line.

• The y-intercept is the point where a line crosses the y-axis.

• The y-intercept is the slope of a line.

• The y-intercept is the point where a line crosses the x-axis.

What does the y-intercept represent in a linear equation?

• The slope of the line.

• The point where the line intersects the y-axis.

• The point where the line intersects the x-axis.

• The rate of change of the line.

If a linear equation has a y-intercept of 5, what does that mean?

• When x=0, y=5.

• When x=5, y=5.

• When x=0, y=0.

• When x=5, y=0.

Explain how to interpret the y-intercept in a real-world context.

• The y-intercept represents the value of the dependent variable when the independent variable is negative.

• The y-intercept represents the value of the dependent variable when the independent variable is at its maximum.

• The y-intercept represents the value of the dependent variable when the independent variable is zero.

• The y-intercept represents the value of the dependent variable when the independent variable is undefined.
