Question #81e06

Answer 1

`y=-1/10x+3.1`

`y=mx+b` is the slope-intercept form.

Explanation:

Find the slope, which is

`m = (y_2-y_1)/(x_2-x_1)`

`m = (2-3)/(11-1)=-1/10`

Find `b` by substituting the `x` and `y` values into `y=mx+b`

`3=(-1/10)(1)+b`

`b=3.1`

Now you know your `m` (slope) value and `b` value. substitute back into the equation `y=mx+b` to get the equation

`y=-1/10x+3.1`
