The graph of y = 2x (dashed line) was reflected in the x-axis to create the solid line.   What is the equation of the new line? 

Solve the following proportion A recipe for pancakes uses 2 cups of flour for every 3 cups of milk. If you want to make enough pancakes for the class, you need to use 12 cups of milk. How many cups of flour will you need?

Simplify the following Power Expressions: a)   b)   c)   d)

a) Determine the “first difference” for the following “linear relation”. First Difference b) State the “y-intercept” for this relation. Use the coordinate form of (x,y) y-intercept (, )

Determine the slope of the line that passes through points (15, -8) and (10, 3). m= rise/run

Volume =   Units

Show how you determined the x and y intercepts.  Verify your answers. 

Entering values point by point takes a lot of time. A COORDINATE RULE can help. Instead of entering individual coordinates for a shape that has been translated 2.5 units to the left and 1 unit down, you can type/write (x−2.5,  y−1) to find its vertices.
