Question

Which ordered pairs in the form (x, y) are solutions to the equation

4x−5y=24

Select each correct answer.
A: (1, −4)
B: (−9, −12)
C: (6, 0)
D: (4, 8)

Answer 1

Simply put and very ironically, use the answer choices of the question to answer your question.

You want to put all of these values into \(\sf{4x-5y=24}\)

\(\sf{
A)~~4(1)-5(-4)~~~~~=24 \\
B)~~4(-9)-5(-12)=24 \\
C)~~4(6)-5(0)~~~~~~=24 \\
D)~~4(4)-5(8)~~~~~~~~=24 \\
}\)

Then, you just solve for each of them, and if they equal up to \(\sf{24}\), then they are a valid point on the graph.


I simplified the answer choices here for you:
\(\sf{
A)~~~~~~~4~~+20~=24 \\
B)~~-36+60~=24 \\
C)~~~~~~~24+0~~~=24 \\
D)~~~~~~16~-40~=24 \\
}\)
