  1. Question: Plot the line y = 3x + 2.some text
    • Answer: For x = 0, y = 2 (point (0, 2)). For x = 2, y = 8 (point (2, 8)). Plot these points and draw the line.
  1. Question: For y = -2x + 4, plot the point where x = -1.some text
    • Answer: Substitute x = -1 to get y = 6. Plot (-1, 6).

Algebra Practice Questions for Middle School

Algebra in middle school lays the foundation for understanding mathematical concepts that are crucial for advanced studies. In the following section, you'll find practice questions with answers tailored for middle school students, focusing on basic algebra, forming and solving equations, and interpreting graphs. 

Basic Algebra

  1. Question: Solve for x: 3x + 4 = 19.some text
    • Answer: x = 5. (Subtract 4 from both sides, then divide by 3.)
  2. Question: Solve for x: 2x - 5 = 15.some text
    • Answer: 2x = 20 (add 5 to both sides). So, x = 10 (divide by 2).
  3. Question: Solve for x: 3x + 7 = 2x + 14.some text
    • Answer: x = 7 (subtract 2x and 7 from both sides).
  4. Question: Solve for x: 4(x - 2) = 2(x + 6).some text
    • Answer: 4x - 8 = 2x + 12 (expand). Then, 2x = 20 (subtract 2x and add 8). So, x = 10 (divide by 2).
  5. Question: Solve for x: 5(x + 3) - 2x = 3(x - 2) + 9.some text
    • Answer: First, expand both sides: 5x + 15 - 2x = 3x - 6 + 9. Simplify to 3x + 15 = 3x + 3 (combine like terms). Subtract 3x from both sides: 15 = 3.

Forming and Solving Equations

  1. Question: A garden is 3 times as long as it is wide. If the garden's perimeter is 64 meters, what are the garden's length and width?some text
    • Answer: Length = 24 meters, Width = 8 meters. (Let the width be x, so the length is 3x. The perimeter formula, 2l + 2w = 64, leads to 2(3x) + 2x = 64, solving for x gives the width, and 3x gives the length.)
  1. Question: For a class trip, the number of students is triple the number of teachers. If the total number of people going on the trip is 80, how many students and teachers are going?some text
    • Answer: Students = 60, Teachers = 20. (Let the number of teachers be t, so the number of students is 3t. The equation is t + 3t = 80, solving for t gives the number of teachers, and 3t gives the number of students.)
  1. Question: A book has 150 pages more than a booklet. If the total number of pages in both is 450, how many pages does each have?some text
    • Answer: Book = 300 pages, Booklet = 150 pages. (Let the booklet's pages be p, so the book's pages are p + 150. The equation is p + (p + 150) = 450, solving for p gives the booklet's pages, and p + 150 gives the book's pages.)
  1. Question: A fruit basket contains apples and oranges. There are twice as many apples as oranges. If the basket contains 90 fruits in total, how many apples and oranges are there?some text
    • Answer: Apples = 60, Oranges = 30. (Let the number of oranges be o, so the number of apples is 2o. The equation is o + 2o = 90, solving for o gives the number of oranges, and 2o gives the number of apples.)
  1. Question: The number of students in the chess club is 5 less than twice the number in the science club. If there are 45 students in both clubs combined, how many are in each club?some text
    • Answer: Chess Club = 30, Science Club = 15. (Let the number in the science club be s, so the chess club has 2s - 5. The equation is s + (2s - 5) = 45, solving for s gives the number in the science club, and 2s - 5 gives the chess club's number.)


  1. Question: Graph the equation y = 2x + 1.some text
    • Answer: Start at y-intercept (0, 1). Slope = 2 means rise 2, run 1. Plot another point at (1, 3) and draw the line.
  2. Question: Graph the equation y = -x - 3.some text
    • Answer: Begin at y-intercept (0, -3). Slope = -1 means down 1, right 1. Mark (1, -4) and draw the line.

    • Answer: Y-intercept at (0, -2). Slope = 1/2 means up 1, right 2. Place another point at (2, -1) and connect.
  4. Question: Graph the equation y = -2x + 4.some text
    • Answer: Start at (0, 4) for y-intercept. Slope = -2 means down 2, right 1. Plot (1, 2) and draw the line.
  5. Question: Graph the equation 2y - 3x = 6.some text
    • Answer: Rearrange to y = 3/2x + 3. Y-intercept (0, 3), slope = 3/2. Up 3, right 2 from (0, 3) to (2, 6) and graph.
