Directions: These questions pertain to linear equation graphs. Choose the correct answers.

1.
Which equation could represent the graph at the right? (Points with integer coordinates are shown.)
np1

Choose:
 
-2x + y = 5
  2x + y = 5
  y = 2x + 5
  y - 3 = 2(x - 1)



2.
What is the y-intercept of the graph
0.25x + 0.05y = 1.00?
gg5

Choose:
 
(0,1)
(0,2)
 
(0,10)
(0,20)



3.
Which statement describes the graph of y = 7?
gg3

Choose:
 
A horizontal line with no "run" and infinite "rise".
 
A horizontal line with no "rise" and infinite "run".
  A vertical line with no "run" and infinite "rise".
  A vertical line with no "rise" and infinite "run".



4.
If the x-intercept of a linear graph is 1 and the y-intercept is -3, what will be the new x-intercept and y-intercept if the line is translated (moved) up 3 units?
(State the x-intercept first.)
gg2
Choose:
 
4 and 0
0 and 0
 
-2 and -6
0 and 4



5.
If one point on the graph of a line is (-1,8) and the slope is -2, find the coordinates of the y-intercept of the line.
gg7
Choose:
 
(0,6)
(0,-1)
 
(0,8)
(0,10)



6.
Write the equation of a line whose graph has no y-intercept, but will have an x-intercept of -3.
gg1
Choose:
 
y = -3
x = -3
 
y = 3
y = x



7.
A line passes through the points (x,2) and (3,-4) and has a slope of 2. What is the value of x?
gg6
Choose:
 
x = 0
x = 2
 
x = 1/6
x = 6



8.
Which of the following equations could describe the line seen in the graph at the right? (Check all that apply, and hit SUBMIT!)
 
12x - 4y = 8

y = 3x - 2

y - 4 = 3(x - 2)

3x - 4y = 8

3x - y = 2

y - 2 = 3(x - 4)

y + 5 = 3(x + 1)

newguycry

Choose:
 
(1, 1.5)
(0.5, 1.75)
 
(-0.75, 2.5)
(2, 1)



10.
Which of the following equations have the same slope as the line seen in the graph at the right? (Check all that apply, and hit SUBMIT!)
 

y - 1 = -½(x + 3)

y = 2x + 7

y - 4 = 3(x - 2)

x + 2y = 8

-x + 2y = 2

2y = -x

y + 8 = 2(x + 4)
