Question

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

Answer 1

7x-48

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

`(y_2-y_1)/(x_2-x_1)\\\\(8-(-6))/(8-6)\\\\(14)/(2)=7`

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
