Question

The question says to select all that satisfy the function, which is y= -4x - 3/4

A  (1, 3 1/4)

B  (-1, 2 1/4)

C  (3, -12 3/4)

D  (15 1/4, -4)

 

What does it mean, 'satisfy the function'? How do I find the answer?

There's another one, too.

 

Select all that satisfy the function, which is y= -1/2x + 4

A  (-1, 3 1/2)

B  (1, 3 1/2)

C  (2 1/2, 3)

D  (2, 3)

Answer 1

Kyle, you should know that points are listed as (x,y). Plug in your values for x and y and see which make the equation true.

 

3 1/4 = -4(1) - 3/4

3 1/4 = -4 - 3/4

3 1/4 = -4 3/4

 

Hey, that's not true. A does not satisfy the function.
