Practice 16D

Create a graph of all the data points from the table. Draw a line that would extend to the edges of the plane. Use the graph to estimate the number plates prepared after 6 minutes.

Based on the table, what would be the correct slope (m) of the line?

Based on your graph in question 1, how many plates would have been already prepared at the start of the server's shift?

Hint: This is the initial value when x = 0 also known as the y-intercept of the graph.

Use the slope and y-intercept of the graph in question #1 to write an equation of the line in slope intercept form. Let y = the number of plates and x = the number of minutes.

Does the graph have a positive or negative slope?

Estimate the y-intercept and interpret its meaning.

Does the graph have a positive or negative slope?

Estimate the y-intercept and interpret its meaning.

Hint: Use the coordinate pairs: (2, $49) and (4, $67) to find the slope and y-intercept before writing the equation in slope-intercept form.

Let y = the total cost of the cable package and x = the number of movie channels

Hint: Use the coordinate pairs: (12, $61) and (18, $79) to find the slope and y-intercept before writing the equation in slope-intercept form.

Let y = the total cost of the bouquet and x = the number of roses
