Complete the equation of the line through (6,-6) and (8,8). Y =

7x-48

Step-by-step explanation:

we want our equation to look something like this

y=mx+b

let's start by solving for m (the slope) using the slope formula

Which means, so far, our equation looks like this

y=7x+b

now we just need to solve for B

We can do this by plugging in a set of coordinates

-6=7*6+b

-6=42+b

-48=b

which means our equation is

7x-48

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
