7x+y=-9
-3x-y=5No solution(1,8)(-2,-3)(-1,-2) - 14. Multiple ChoiceWrite the equation of the line.y = -1/3x - 2y = 1/3x - 2y = 3x - 2y = -3x - 2
- 15. Multiple ChoiceWrite the equation of the line.y = -2/3x + 4y = 2/3x + 4y = 3/2x + 4y = -3/2x + 4
- 16. Multiple Choice
If you where to graph the equation y = 2x - 3, how would you begin?
By going up 2 and over 1
By placing a point at -3 on the y-axis
By going down 2 and over 3
By going up 2 and over 3
- 17. Multiple Choice
How would you graph y = 1/2 x + 2
Allow your pencil to aimlessly drift across your paper until- Behold! A line is formed!
Place a point at 0.5 on your y-axis. Then go up 2 and right 1 and place your second point. Draw your line.
Start at the origin and go down 1 and over 2 again and again until you see your line.
Place a point at 2 on the y-axis. Then from that point go up 1 and right 2 and place your second point. Draw your line. (Or make a t-chart)
- 18. Multiple Choice
Which method may be fastest if both equations are in standard form with the x's and y's lined up?
graphing
substitution
elimination
