Writing Linear Equations

Question 1

Which equations represent the data in the table? Check all that apply.

Revolt · Accepted Answer

y – 6 = (x + 2); y – 1 = –(x – 2); y – 3.5 = –1.25x

Question 2

Ava wants to figure out the average speed she is driving. She starts checking her car’s clock at mile marker 0. It takes her 4 minutes to reach mile marker 3. When she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0.

Revolt · Accepted Answer

✔ 0.75; mile(s) per minute: 0.75; n – 6 = 0.75(t – 8)

Question 3

n – 4 = 0.4(t – 3)✔ n – 6 = 0.75(t – 8)n + 3 = 1.33(t + 4)n + 8 = 2.5(t + 6)

Revolt · Accepted Answer

✔ n – 6 = 0.75(t – 8)

Question 4
