Question

Y=mx+b m= rise/run = change in Y/change in x/ b= y-intecept.

Answer 1

y = -
`(2)/(8)` + 5

Explanation:

You have all that you need

(y = mx+b, m= rise/run which is the change in y/change in x, b = y-intercept.)

so now we just need to put it to use!

Let's take y = mx + b and break it into two parts. We need the b and the m. The b is easier, because we can conclude by looking at the graph it is equal too 5. Here is our equation so far:

y = mx + 5

Now we need to solve for m:

`(rise)/(run) = (2)/(8)`

The line is going dowards, so the slope (m) is negative.

Here is our final answer:

y = -
`(2)/(8)` + 5
