 Graphing Linear Equations Practice Terms of Use    Contact Person: Donna Roberts  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.) 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? Choose:
 (0,1) (0,2) (0,10) (0,20)

3.
Which statement describes the graph of y = 7? 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.) 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. 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. 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? 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) (Points with integer coordinates are shown.)

9.
Consider the equation 2x + 4y = 8. Which of the following points does not lie on this straight line? 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) (Points with integer coordinates are shown.)
