Question

Write an equation in point-slope form for the line through the given point with the given slope

(9,-1) ; m=4/5

Answer 1

see explanation

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m =
`(4)/(5)` and (a, b) = (9, - 1), hence

y - (- 1) =
`(4)/(5)`(x - 9), that is

y + 1 =
`(4)/(5)`(x - 9) ← in point- slope form
