Aline passes through (2, −1) and (4, 5). which answer is the equation of the line? a. −3x + 5y = 13 b. −3x + y = −7 c. −3x + y = 17 d. −3x + 5y = −13 which answer is an equation in point-slope form for the given point and slope? point: (1, 9); slope: 5 a. y − 1 = 5 (x + 9) b. y − 9 = 5 (x − 1) c. y + 9 = 5 (x−1) d. y − 9 = 5 (x+1)

Step-by-step explanation:

1) We have equation of line passing through (x₁,y₁) and (x₂,y₂) given by

   (x₁,y₁) = (2, −1) and (x₂,y₂) = (4, 5)

Substituting

Option B is the correct answer.

2) Point slope form of line is given by

                 y-y₁ = m(x-x₁)

        (x₁,y₁) = (1, 9) and m = 5

     Substituting    

               y-9 = 5(x-1)        

     Option B is the correct answer.
