Points A and B are on the line y = 2x – 1 Complete the coordinate pairs for:
(a) point A A= ( 5, )
(b) point B B= ( ,-1 )

EXPLANATION NEEDED.​

Step-by-step explanation:

a) A(5, __)

Plugin x = 5 in the equation.

y = 2x -1

y = 2*5 - 1

  = 10 - 1

y = 9

A(5 , 9)

b) B(___ , -1)

Plugin y = -1 in the equation

y = 2x -1

-1 = 2x - 1           {add 1 to both sides}

-1 + 1 = 2x

0 = 2x

2x = 0

x = 0

B(0 , -1)

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4
