Question

Find the point slope equation for the line that passes through the points (1,-9) and (-10,101)

Answer 1

Answer:

( y + 9 ) = -10( x - 1 )

Step-by-step explanation:

First we calculate the slope

$m=\frac{-9-101}{1-(-10)} =-10$

Then we choose a point it could be (1,-9) or (-10,101), I choose (1,-9), the slope point form is (y-y1)=m(x-x1)

( y - (-9) ) = -10( x - 1 )

( y + 9 ) = -10( x - 1 )

it could be also...

( y - 101  )= -10( x- (-10) )

( y - 101 ) = -10( x + 10 )
