The following answer to this is 1. B
2.D

Answer:

Question 3

C. [tex] y-9 =1/2(x-1)[/tex]

Question 4

D. [tex] y+5 =3(x+2)[/tex]

Step-by-step explanation:

Question 3:

Equation of line in point slope form is given as:

[tex] y-y_1 =m(x-x_1)[/tex]

Plug m = 1/2, [tex] x_1 = 1, \:y_1 = 9 [/tex] in the above equation, we find:

[tex] y-9 =1/2(x-1)[/tex]

This is the required equation of the line.

Question 4:

Equation of line in point slope form is given as:

[tex] y-y_1 =m(x-x_1)[/tex]

Plug m = 3, [tex] x_1 = - 2, \:y_1 = - 5[/tex] in the above equation, we find:

[tex] y-(-5) =3[x-(-2)][/tex]

[tex] y+5 =3(x+2)[/tex]

This is the required equation of the line.
