Graphing Linear Functions in Standard Form

What is the standard form of a linear equation?

• ax^2 + by = c

• ax + by^2 = c

• ax + by = c

• ax / by = c

How do you find the x-intercept of a linear equation in standard form?

• Divide both sides by y

• Multiply both sides by x

• Set x to zero and solve for y

• Set y to zero and solve for x

What does the cover-up method help to determine?

• The slope of the line

• The intercepts of the line

• The minimum value of the function

• The maximum value of the function

What is the result of converting the equation 2x - 20 = 5y into standard form?

• 2x - 5y = 20

• 5y + 2x = -20

• 5y - 2x = 20

• 2x + 5y = -20

How do you graph a line if you know the intercepts?

• Connect the intercepts with a curved line

• Connect the intercepts with a straight line

• Draw a circle through the intercepts

• Plot only the intercepts without connecting them

What does the equation 'x = -4' represent on a graph?

• A horizontal line at x = -4

• A vertical line at x = -4

• A horizontal line at y = -4

• A vertical line at y = -4

What is the y-intercept of the equation 2x + y = 8?

• 8

• 2

• 0

• 4

In the context of the banquet planning problem, what does 6x + 12y = 180 represent?

• The total cost of tables

• The total area of the banquet hall

• The total number of people seated

• The total number of tables

If you have 30 small tables and no large tables, how many people can you seat?

• 180 people

• 30 people

• 12 people

• 360 people

What combination of tables will also seat 180 people, given the choices 6 small and 12 large, 25 small and 26 large, or 12 small and 9 large?

• All of the above

• 12 small and 9 large

• 25 small and 26 large

• 6 small and 12 large
