Question

the graph of 8y+3x=0 is:
1. a line that is neither horizontal nor vertical
2. a vertical line
2. a horizontal line
3. not a line

Answer 1

solve for y

Answer 2

it goes through (0,0) right?
plug in x=1, and tell me what point you get.

Answer 3

then you should be able to tell right away if this line is horizontal, vertical or neither (based on which points it goes though).

Answer 4

Or, solve for y, as raffle_snaffle advised.

Answer 5

"Write an equation of the line that passes through the given point and is parallel to the graph of the given equation."
#1. (3,2); y=3x-2
#2. (-4,-1); y=2x+14
#3. (-8,6); y=-1/4x+5
#4. (6,2); y=2/3x+19
#5. (10,-5); y=3/2x-7
#6. (-3,4); y=2

"Determine whether the graphs of the given equations are parallel, perpendicular, or neither. Explain."
#7. y=4x+5
-4x+y=-13
#8. y=7/9x-7
y=-7/9x+3
#9. y=7/8
x=-4
#10. y=-6x-8
-x+6y=12
#11. 3x+6y=12
y-4=-1/2(x+2)
#12. y=4x+12
x+4y=32

"Determine whether each statement is always, sometimes, or never true. Explain."
#13. Two lines with different slopes are perpendicular.
#14. The slopes of vertical lines and horizontal lines are opposite reciprocals.
#15. A vertical line is perpendicular to the x-axis.

Answer 6

It would be 2. a horizontal line, right?

Answer 7

yep
