Question

Relationship B has a greater rate than Relationship A. This graph represents Relationship A.

Which equations could represent Relationship B?

Select each correct answer.

y = 2.2x

y=1/2x

y = 3x

y = 1.4x

Answer 1

Given relationship B to be "y" and relationship A to be "x"
the coefficient (numerical multiplier) of variable "x" should be a positive number greater than 1 (to represent the increased rate)

i.e. \(y=mx\) with \(m\gt0\)
based on this, which answers are valid?

Answer 2

....

Answer 3

Wait, why is this in English LOL

Answer 4

I'm so confused

Answer 5

Answer 6

oh

Answer 7

Relationship B will be "y" since we're looking for an equation involving it. The original relationship "x" will be Relationship A.

"Relationship B has a greater rate than Relationship A" means that \(y\) is \(x\) multiplied by some factor \(m\) which is greater than 1 (otherwise the rate wouldn't increase):\[y=mx\text{ where the value }m\gt1\]

Here's a tip: the first choice would be correct as \(m=2.2\gt1\).

tbh I typed that first part while in the last 10 minutes of organic chemistry, mb
