Question

39. State the equation for the line described below.

40. State the equation of the line that passes through the points (–7, 5) and (–12, 4).

Picture is attached

Answer 1

Explanation:

39). y =
`-(7)/(8)` x + 3

40). m =
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`

y -
`y_(1)` = m( x -
`x_(1)` )

(- 7, 5)

( - 12, 4)

m = ( 4 - 5 ) / ( - 12 + 7) = 1/5

y - 5 = (1/5)(x + 7) ⇒ y =
`(1)/(5)` x + 6.4
