PLS HELP!!!
Find the slope of a line perpendicular to 2x-y=16

Answer 1

@Vocaloid

Answer 2

first you will arrange 2x - y = 16 in y = mx + b form to find the slope

then you will take the reciprocal and multiply by -1 to get the solution

Answer 3

-y=2x+16

Answer 4

have to be careful, re-arrange doesn't just mean move the terms around, you have to perform the operations necessary to move the terms

for example, for 2x - y = 16 you have to add y to both sides to "move" y to the other side

Answer 5

2x+y-y=16+y?

Answer 6

good, and simplifying that gives us

2x = 16 + y

now subtract 16 from both sides to convert to y = mx + b form then find the slope

Answer 7

2x-16=16-16+y

Answer 8

good so y = 2x - 16 so the slope of the original line is...?

Answer 9

-14+y

Answer 10

hm, not quite

compare y = mx + b and y = 2x - 16, what is m?

Answer 11

2

Answer 12

but why did you change it to y=2x-16?

Answer 13

shouldn't it have been -14x+y?

Answer 14

you cannot combine 2x and 16 to get -14 because they are not like terms

Answer 15

it would have to be 2x-16x

Answer 16

anyway, now we know the slope is 2, we take the reciprocal which means we write 1/2, then multiply by -1 to get -1/2 as the perpendicular slope = the solution

Answer 17

thankx for explaining
