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

• The y-intercept represents the maximum value of the linear equation.

• The y-intercept represents the point where the line intersects the x-axis.

• The y-intercept represents the slope of the line.

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

Graph the line with the equation y = -2x + 4.

• The line with the equation y = -2x + 4 is a horizontal line.

• The line with the equation y = -2x + 4 is a curve.

• The line with the equation y = -2x + 4 is a vertical line.
