Question

Which of the following points lies on the graph of this equation?

y = 1/4x - 1

A. (0, -1)
B. (1, 2)
C. (2, 1)
D. (4, 1)

Answer 1

A. (0,-1)

Explanation:

y = (¼)x - 1

-1 = 0 - 1

-1 = -1

Answer 2

A. (0, -1)

Explanation:

y = 1/4x - 1

Substitute the points into the equation and see if it is true

A. (0, -1)

-1 = 1/4(0) -1

-1 =0-1

-1 = -1 true

B. (1, 2)

2 = 1/4(1) -1

2 =1/4 -1

2 = -3/4 false

C. (2, 1)

1 = 1/4(2) -1

1 =1/2 -1

1 = -1/2 false

D. (4, 1)

1 = 1/4(4) -1

1 =1 -1

1 = 0 false
