b. perpendicular
c.neither

1 answer

To determine whether the lines are parallel, perpendicular, or neither, we can compare the slopes of the two lines.

First, let's put the second equation in slope-intercept form (y = mx + b) by solving for y:

-2x + 8y = 5
8y = 2x + 5
y = (2/8)x + 5/8
y = (1/4)x + 5/8

From the first equation, we can see that its slope is -4. Therefore, the slope of the first equation is -4.

From the second equation, we can see that its slope is 1/4. Therefore, the slope of the second equation is 1/4.

Since the slopes are not equal, the lines are neither parallel nor perpendicular.

Therefore, the answer is c. neither.
