Graphing a linear equation in slope intercept form

The video tutorial explains how to identify and graph a horizontal line in slope-intercept form. It begins by discussing the Y-intercept and the absence of an X term, leading to a slope of zero. The tutorial then demonstrates how to graph this equation by plotting the Y-intercept and drawing a horizontal line through it.

What is the Y-intercept of the equation y = -4?

• (0, 4)

• (0, -4)

• (4, 0)

• (-4, 0)

Why is the slope of the equation y = -4 considered to be zero?

• Because it has a negative Y-intercept

• Because it has no X term

• Because it has a positive Y-intercept

• Because it has an X term

What type of line is formed when the slope is zero?

• Vertical line

• Diagonal line

• Horizontal line

• Curved line

Where should you plot the Y-intercept on the graph for the equation y = -4?

• On the X-axis

• On the Y-axis at -4

• On the X-axis at 4

• On the Y-axis at 4

What remains constant in a horizontal line?

• The intercept

• The slope

• The Y value

• The X value
