Ineed this done in 3 hours and i cant figure it out

1. three out of the four equations listed below are equations of lines that are parallel to each other. which equation does not have a graph that is a line parallel to the other three?

-4x + 3y = 5

9x = -12y

3x + 4y = -16

8y = - 6x

2.
which equation is the slope-intercept form of the equation of the line that passes through (1, 2) and is parallel to 4x - 2y = 6?

y = 2x

y = 4x + 3

y = -2x + 1

y = -2x

3. choose the slope-intercept form of the equation of the line that passes through (-2, 4) and is perpendicular to the graph of 2x + y = -20.

y = -2x

y = 1/2x -3

y = 2x + 8

y = 1/2x + 5

4. which equation has a graph perpendicular to the graph 3y = 2x - 9?

3x + 2y = 7

2x + 3y = 4

y = 2x + 5

-2x + 3y = -7

5. tell whether the lines are parallel, perpendicular, or neither.

9x + 3y = 6
3x + 9y = 6

a. perpendicular

b. parallel

c. neither

6. tell whether the lines are parallel, perpendicular, or neither.
y = 3x - 8
3x - y = -1

a. perpendicular

b. parallel

c. neither
