Question

Which is a solution to the equation y = 2x – 5?
A.(3, 11)
B.(2, 1)
C.(1, –3)
D.(5, –5)

Answer 1

which one do you think?

Answer 2

Insert the coordinates inside the original equation,

Pick everyone and see if they work, but for you to learn I am going to give you an example.

y= 3x +2

(2,2)
(3,11)

(2) = 3(2) +2
2= 8 No, because they do not equal to each other, so reject the coordinate.


Now try this:

(11) = 3 (3) +2
11= 9 + 2
11= 11 Correct, this is the solution to the equation y= 3x+2

This was just an example, follow this and then you can solve your question! :)

I hope this helped, and if you had any question, feel free to let me know.
