Question

Select all that function with -4x+5=y (-4,5)(-19,6)(9,-31)(8,-27)

Answer 1

Answer

(9, -31) and (8, -27)

Step-by-step explanation:

Given the following function

y = -4x + 5

Testing the options

Using (9, -31)

let x = 9 and y = -31

-31 = -4(9) + 5

-31 = -36 + 5

-31 = -31

Hence, (9, -31) satisifies the function y= -4x + 5

Using (8, -27)

let x = 8 and y = -27

-27 = -4(-8) + 5

-27 = -32 + 5

-27 = -27

Hence, (8, -27) satisfy the function y = -4x + 5
