Pls help i rlly need to get my grades up !! The graph below shows a proportional relationship between x and y.What is the constant of

3.5

Step-by-step explanation:

Use point (1, 3.5) on the graph

x = 1, y = 3.5

k = 3.5

2;0.5 ratio proportional value

Step-by-step explanation:

0.5/1 or y=0.5x

Step-by-step explanation:

Y is first and the dot is located at 0.5 and the other dot is at 1 is this what u mean?

0.5

Step-by-step explanation

I'm sure.

1.- T

2.-  (3.5, 1)

Step-by-step explanation:

Hope this helps :3 brainliest?

Step-by-step explanation:

 4

Explanation:

We can pick any (x,y) point on this blue line as long as we don't pick (0,0)

This is because we cannot divide by zero.

Let's say we pick the point (x,y) = (1,4)

The constant of proportionality is found like so

k = y/x

k = 4/1

k = 4

The constant of proportionality is 4

Or we could pick a point like (2,8) to get

k = y/x

k = 8/2

k = 4

We get the same thing.

There are infinitely many points to pick, but in my opinion, it's easiest to stick with (1,4).

As a slight alternative, you can apply the slope formula (pick any two points you want on the blue line) and you should get 4 as well.

Extra info:

         y/x = 4

Step-by-step explanation:

For any point from line for 1 of x we have 4 ys:

x=1→y=4,   x=2→y=8=4×2,   x=7→y=28=4×7

It means:

y = 4x        dividing by x we get:    y/x = 4

Ithink the answer is $2.10
