Question

What is an equation for a direct variation whose graph passes through the point (-10,5) show work

Answer 1

the equation for direct variation is
y = kx , and you have to find 'k' , the parameter

Answer 2

Remember that (x,y)

Answer 3

you can solve for k , if you substitute x = -10, y = 5 , into the equation

Answer 4

So...what @perl said... ^^^

Answer 5

congratulations @StudyGurl14 (turning green)

Answer 6

Thanks, @perl

Answer 7

so k would be -0.5

Answer 8

Right ^

Answer 9

So then the equation would be...?

Answer 10

is that what the question is asking for?

Answer 11

Plug k back into the equation
y=kx

Answer 12

and that's your answer

Answer 13

y = -0.5x

Answer 14

is that the final answer ^?

Answer 15

yep

Answer 16

thanks

Answer 17

anytime. :)
