2. Using the slope you found in question 1, write the equation of the line in slope-intercept form.

• y = x + m

• y = mx + b

• y = mx - b

• y = b + mx

4. Write the equation of the bike path from question 3 in point-slope form using point C.

• y = mx + b

• y - y1 = m(x + x1)

• y - y1 = m(x - x1)

• y + y1 = m(x - x1)

5. A store's sales increased from $200 at 3 PM (point E) to $500 at 6 PM (point F). What is the slope of the sales over this time period?

• 150

• 200

• 300

• 100

6. Write a linear equation that represents the sales over time, using the slope from question 5 and point E.

• y = mx + b

• y = mx^2 + c

• y = mx + (y1 - mx1)

• y = m + x

8. Create a linear equation that models the student's score improvement, using the slope from question 7 and point G.

• y = mx + b

• y = mx - mx1 + y1

• y = mx1 + y1

• y = mx - y1 + mx1

10. Write the equation of the train's route in standard form using the slope from question 9.

• Ax - By = C

• y = mx + b

• Ax + By = C

• C = Ax + By
