Find the equation of the line below (1,-6) (2,-12) ! i don't understand?

We have the points (1, -6) , (2, -12)

Find the slope (m)

m = (y₂-y₁) / (x₂-x₁)

Plug in the values.

m = (-12 + 6) / (2 - 1)

Simplify.

m = -6/1

So, our slope is : m = -6

We are looking for our equation in point-slope form.

Point-slope form : y - y₁ = m(x - x₁)

Simply plug in everything. 

Our given points : (1, -6) and (2, -12)

y - (-6) = -6(x - 1)

Simplify.

y + 6 = -6x + 6

Subtract 6 from both sides.

y = -6x + 6 - 6

Simplify.

So, y = -6x

Your answer is C) y = -6x

~Hope I helped!~

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
