Algebra I and Concepts
Ch. 3 Test Review
Directions
1) Get out a piece of paper, put your name and
“Ch. 3 Test Review” at the top
2) As each slide appears, work through the
problems shown. You may not finish them all,
that is ok! Don’t rush, work through what you
can.
3) When the answer slide is posted, check your
answers, find and correct mistakes. Ask
questions if necessary.
4) Finish any questions by looking up the review on
my website
5) This will be turn in on MONDAY with your
homework
Find the x and y intercepts of the lines
graphed
Find the x and y intercepts of the lines
graphed
X-int: (-5, 0)y-int: (0, 3) X-int: (7, 0) y-int: (0, 7)
Find the x and y intercepts of the
following equations
1) -5x + 8y = -40
2) x – 3y = 15
Find the x and y intercepts of the
following equations
1) -5x + 8y = -40
X-int: (8, 0)
Y-int: (0, -5)
2) x – 3y = 15
x-int: (15, 0)
y-int: (0, -5)
Graph using the x and y intercepts
1) 3x – 4y = 12
2) -x – 3y = 9
Given two functions, determine any
similarities and differences of their graphs.
(Hint: Use cover-up to graph)
1) 3x – 4y = 12
2) -x – 3y = 9
Find the slope of the line through the 2 points,
then use the slope to classify the line as,
horizontal, vertical, or oblique
1) (-3, 7) (-3, 4)
2) (-4, 3), (-2, 1)
3) (5, 2), (-6, 2)

Mrs. Huseman and Ms. Howard are going to put
up Christmas lights. They lean a ladder against
the house and the top of the ladder touches the
house at 12 feet above the ground. The base of
the ladder is 6 feet from the side of the house.
a) Draw a picture of the situation and label
everything!
b) What is the slope of the ladder as a positive
number?
