Question

Which equation represents a line perpendicular to the line whose equation is 2y − 5x = 10?
A. 5y - 2x = 25
B. 5y + 2x = 10
C. 4y - 10x = 12
D. 2y + 10x = 8

Answer 1

if it is perpendicular, then the slopes are opposite

Answer 2

2y-5x=10
2y=5x+10
y=(5/2)x+5

Answer 3

ohh ok

Answer 4

you need to put all of your options into slope intercept form and whichever is (-2/5)x is it

Answer 5

thx man
