Answer:
Explanation:
the equation of a line in
point-slope form
is.
xy − y1 = m(x−x1)
where m is the slope and (x1 - y1 ) a point on the line
to calculate m use the
gradient formula
m= y2−y1
x2−x1
let ( x1 , y1) =( 8, 5) and ( x2 ,y2 ) = (0, −4)
⇒ m= -4-5/0-8= -9/-8= 9/8
using m= 9/8 and (x1- y1) = (8,5) then
y-5= 9/8(x-8)
