Question

Let c be any constant number. Which of the following will always be perpendicular to -4x + y = -2?

Answer 1

and the following are?

Answer 2

Y=1/4X+C
Y=4X+C
Y=-4X+C
Y=-1/4X+C

Answer 3

can you find slope of lines? the product of slopes of two lines perpendicular to each other is -1

Answer 4

I DONT KNOW HOW TO FIND SLOPE

Answer 5

slope is also called gradient. do you know how to find gradient?

Answer 6

no

Answer 7

In a line Ax+By+c=0
slope=-B/A
can you do it now? just try. you can do it.
find slopes.
the product of slopes of two lines perpendicular to each other is -1

Answer 8

i got y=4x+c is this right?

Answer 9

oops! i made a mistake! typo.
slope=-A/B
Now do it.

Answer 10

so i got y=-4x=C is this right?

Answer 11

what is the slope of given line?

Answer 12

4?

Answer 13

yep.
now let, slope of anothe line perpendicular to it be x
therefore, 4x=-1
or, x=-1/4
so, the line which has the slope -1/4 is your answer.

Answer 14

ohh okay thank you

Answer 15

the correct answer is y=-1/4x+c
