Question

Write an equation in point-slope form for the line through the given point with the given slope. (9,-1); m=4/3. I need help!

Answer 1

$y - y1 = m(x - x1)$

$y - (-1) = \frac{4}{3} (x - 9)$

$y + 1 = \frac{4x - 36}{3}$

$y + 1 = \frac{4x}{3} - 12$

$y = \frac{4x}{3} - 13$

Answer 2

$(y-y_{1} )=m(x-x_{1})$

$m= \frac{4}{3}$

$y_{1}=-1$

$x_{1} = 9$

$(y-(-1) )= \frac{4}{3} (x-(9))$

$(y+1)= \frac{4}{3} (x-9)$
