Suppose the value of yy and the value of xx vary together at a constant rate of change (so that Δy=0.75⋅Δx), and y=1.5 when x=3.

  1. Suppose the value of xx varies from x=3 to x=6.75.

    1. How much did the value of x change?

      Δx=

    2. How much did the value of y change over this interval of x?

      Δy=  

  2. What is the value of y when x=6.75?
