Question #570e2

Answer 1

`y=-4x+4`

Explanation:

1. Use point slope equation: `(y_2-y_1)/(x_2-x_1)`
   `(-8-4)/(3-0)=-12/3=-4`
2. `f(0)=4` They give you the y-intercept in this problem.
3. Apply to slope equation: `y=mx+b`
4. Linear function: `y=-4x+4`
   Note: To check your work, graph the linear equation and see if the points match at `(0,4)` and `(3,-8)`.
