• A calculator

What happens when you substitute any x-value into the equation y = -4?

• You get different x-values

• You get y = 0

• You get y = -4 regardless of x

• You get different y-values

What type of line is formed when graphing the equation y = -4?

• A curved line

• A vertical line

• A horizontal line

• A diagonal line

When x = -1, what can y be?

• Any value

• Only zero

• Only negative values

• Only positive values

What type of line is formed when graphing the equation x = -1?

• A vertical line

• A curved line

• A horizontal line

• A diagonal line

What should you do after filling out the table of values?

• Ignore the table

• Change the values

• Graph the points

• Erase the table

What is the purpose of using a table of values in graphing?

• To solve equations

• To determine the y-intercept

• To graph a line

What should you do if you encounter an equation like y = or x = by itself?

• Ignore it

• Explore the pattern it forms

• Solve for y

• Change the equation

What is the final advice given by the teacher?
