Joshua needs to come up with ordered pairs that make up the line for this linear function- f(x)=4x-1.

Answer 1

(x,4x-1) plug in any value for x

or since y=4x-1 then 4x=y+1 and x=y/4 +1/4

so the ordered pair in terms of y is

(y/4 + 1/4, y) plug in any value for y

Answer 2

Plug in different values of x and solve. e.g. if x = 1, f(x) = 3

As an "ordered pair" this is (1, 3)

Answer 3

If x= -2, f( -2 ) = 4(-2) -1 = -8 -1 = -9 ; (-2, -9 )

If x = -1, f( -1 ) = 4(-1) - 1 = -4 -1 = -5 ; (-1 , -5 )

If x = 0, f( 0 ) = 4(0) - 1 = 0 - 1 = -1 ; (0 , -1 )

If x = 1, f( 1 ) = 4(1) - 1 = 4 - 1 = 3 ; ( 1, 3 )

If x = 2 , f( 2 ) = 4(2) - 1 = 8 - 1 = 7 ; ( 2, 7 )
