Which lines are perpendicular to 2x−7y=−25? Select all that apply. a. y=2/7x -6
b. 7x+2y=−10
c. y−13=7/2(x+8)
d. 14x+4y=41

B and D

Step-by-step explanation:

slope = 2/7

perpendicular equals negative reciprocal

so slope must be -7/2

A = 2/7

B = -7/2

C = 7/2

D = -7/2

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
