Complete the following questions to practice the skills you have learned in this lesson.

  1. Evaluate 140 − 20 9 − 12 mentally.
  1. Find the slope of the line that goes through the points ( 1 , − 3 ) and ( 2 , 4 ) .:
  1. Write the equation of the line in slope-intercept form that goes through ( 0 , 3 ) and has a slope of 1 4 .
  1. 4 x − y = − 3
  2. y = 3 x + 1 4
  3. y = 1 4 x + 3
  4. y = − 1 4 x + 3
  1. Write the equation of the line that passes through ( 2 , − 1 ) and has a slope of − 1 2 in point-slope form.
  1. 2 x + y = 0
  2. y = − 1 2 x
  3. y + 1 = − 1 2 ( x − 2 )
  4. y = − 1 2 x − 1
  1. Select two equations that are correctly in standard form.
  1. 6 x − 3 y = 3
  2. − 4 x + 5 y = 9
  3. 1 2 x + 3 y = 8
  4. 5 x + 2 y = 9
  5. 5 y + 2 x = 10
  1. Write y = 4 x − 2 in standard form. Hint: Do not include spaces in your answer.
