A line L passing through the point (6, -13) is parallel to the line which passes through (7, 4) and (-3, 9). Find the equation of the line L.

A.

y = 12x10

B.

y = 12x+10

C.

y = 12x10

D.

y = 12x+10

Correct answer is C

(7, 4) and (-3, 9) = (y1,x1)(y2,x2)

slopem1 of the points(7, 4) and (-3, 9) = y2y1x2x1

 m1=9437=510=12

m1=m2 ( condition for parallelism)
Since the line L passes through the point (6, -13) and is parallel to the points (7, 4) and (-3, 9)

12=y(13)x6

= 12=y+13x6

= 12(x6)=y+13

12x+3=y+13

12x+313=y

∴ y = 12x10
