Choose the option that correctly represents the equation through the points

(2,48) and (5, 750).

After noon, the number of people in Mal-Wart grows steadily until 6:00 p.m. If the equation y=228+58x represents the number of people in the store x hours after noon:

How many people were in the store at noon? This is your starting amount.

For the sequence 10.3,11.5,12.7,…, 

Wade wrote t(n)=9.1+1.2n

Dwayne wrote t(n)=10.3+1.2(n−1).

Make a table for the first four terms of each of their sequences. Are both forms of the equation correct?

• Yes both are correct

• No only Wade's is correct

• No only Dwayne's is correct

• Neither are correct.

Choose the dimensions below that would lead to the rectangle on the left.

• (3x-2)(3x-2)

• (9x-4)(x-1)

• (3x+1)(3x+4)

• (9x+2)(x+2)
