the y-coordinate of the point where the graph of a line crosses the y-axis. (x is always 0 and y can be any number)

• Trend line

• Scatter plot

• Slope

• y intercept

The linear regression equation for the data is  y = 1.5x + 12.  Interpret the slope of the equation.

• The slope is (0, 1.5).  It means that a pizza with 0 toppings will cost $1.50.

• The slope is 1.5.  It means that it costs $1.50 per topping.

• There are 1.5 toppings.
