Since the line is parallel therefore it's slope must be the same which is 5.

So we have the equation:

y = 5x + b

Since it passes through the points (2 , -1)

-1 = 5(2) + b

-1 = 10 + b

b = -11

therefore the equation of the line is :

y = 5x - 11

So we have the equation:

y = 5x + b

Since it passes through the points (2 , -1)

-1 = 5(2) + b

-1 = 10 + b

b = -11

therefore the equation of the line is :

y = 5x - 11
