Question

What is the equation for this graph?

Answer 1

y=5/2x or y=2.5x

Explanation:

Answer 2

`y=(5)/(2) x`

Explanation:

Notice is a line, The equation for a line can be found as the following:

`y-yo=m(x-xo)`
We need to find the slope.

First take two points of the graph
(0,0) the origin and (4,10) for example. Notice i do assume the X value is 4 for Y=10, since the cropping for the picture doesn't show the exact values for X .
Then the slope is given by equation:

`m=(y-yo)/(x-xo)\\`

`m=(10-0)/(4-0) =5/2`

then the equation is


`y-0=(5)/(2) m(x-0)`

`y=(5)/(2) x`
