Question

The answer for this problem Find the equation of line j.The blue line is line j

Answer 1

`y=-(1)/(5)x`

Step-by-step explanation

As we can see, line j passes through the origin, so its y-intercept is zero and the equation has the form,

`y=mx`

To find the slope we have to use the formula,

`m=(\Delta y)/(\Delta x)`

In this graph,

Δy = 1 and Δx = 5, but the line is inclined to the left, so the slope is negative,

`m=-(1)/(5)`

And the equation is,

`y=-(1)/(5)x`
