Question

WILL GIVE BRAINLIEST PLS HELP

a direct variation function contains the points (2, 14) and (4,28). Which equation represents the function?

y = x/14
y = x/7
y = 7x
y = 14x

if you need to see those numbers on my computer i put an image pls help me!!

Answer 1

direct variation mean x =ky so y = x/k

(2,14) mean y = kx so 14 = k*2 so 14 = 7*2 so 14 = 14

(4,28) mean y = kx so 28 = k*4 so 28 = 7*4 so 28 = 28

from these result that the 3rd choice is right sure

Answer 2

Answer:

y=7x

Step-by-step explanation:

You divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points to find the slope.
