Name: ___________________________________
Algebra One Summer Review Packet (2019)
Stevenson High School
This packet must be completed the summer before entering Algebra 1. These skills are necessary for a
successful year in this course. Please review the notes for each section and complete all subsequent practice
problems. Be sure to show all of your work. This packet must be completed in its entirety and be ready to be
submitted on the first day of school. A short quiz on these topics will be given on the first Friday of school. If
you’re stuck on something or need more practice, look it up online (Kahn Academy is a great practice
resource with videos). https://www.kutasoftware.com/free.html is also a great resource for free worksheets
and answer keys. Have a great summer—we’ll see you in the fall! ☺

• Substitute the variables with their given
values.
• Each time you substitute a variable with a
number, use parentheses around the number.
• Use Order of Operations to finish the problem.

Idea #9: Graphing a Line by Making a Table of Values
EXAMPLE: Graph 𝑦 = −4𝑥 + 8.
x 𝒚 = −𝟒𝒙 + 𝟖 y (𝒙, 𝒚)
4 𝑦 = −4(4) + 8 -8 (4, -8)
2 𝑦 = −4(2) + 8 0 (2, 0)
1 𝑦 = −4(1) + 8 4 (1, 4)
121. 𝑦 = 3𝑥 − 7
x 𝒚 = 𝟑𝒙 − 𝟕 y (𝒙, 𝒚)
4
1
0
122. 𝑦 = 2𝑥 − 1
x 𝒚 = 𝟐𝒙 − 𝟏 y (𝒙, 𝒚)
5

123. 𝑦 = 7 − 2𝑥
x 𝒚 = 𝟕 − 𝟐𝒙 y (𝒙, 𝒚)

STEPS:
1. Plug x-values into the original
equation to solve for y.
2. The x you plugged in and the y
value you solve for in step one
become your ordered pair.
3. Plot ordered pairs and draw in line
connecting points.
