Answer:
4) y = 2x - 7
Step-by-step explanation:
First we have to find the slope by using the following formula....
let (3, - 1) be
, let (8, 9) be
, and m be the slope, then....

Now that we know the slope we can find the equation of the function by using point-slope for of the function which look like this.....
