Question

Prove that y=7x-2 and y-7x=5 are parallel lines

Answer 1

Answer:

Proved

Step-by-step explanation:

First write in correct form ax +by +c=0

               7x-y-2=0      .. . . . .. . . .. . ..  .. . ..(a1=7 ,b1=-1 ,c1=-2)

               7x-y+5=0       . . . . . . . . . . . . . . . (a2=7 ,b2=-1 , c2=5)

            if the equation follows a1/a2=b1/b2$\neq c1/c2$ then the line is parallel and has no solution.

                     7/7=-1/-1$\neq -2/5$

             it follows the rule of inconsistent, so the line is parallel
