A line passes through the point (-9,9) and has a slope of 2/3 . Write an equation in point-slope form for this line.

Respuesta :

Point slope form should be: y - 9 = 2/3x + 6
point slope is 

y-y1 = m (x-x1)

we have (x1,y1) = (-9,9)  ........ slope = m = 2/3  ... now plug and chug

y - 9 = (2/3) (x - (-9))

y= 2/3x + 15

hope that helps
