What are all the coordinates that are solutions to the equation -2x + 4y = -10

(x , 1/2x - 5/2)  where x is a real number.

Step-by-step explanation:

-2x + 4y = -10 ⇔ 4y = 2x - 10 ⇔ y = 1/2x - 5/2

then any couple of the form (x , 1/2x - 5/2) is a solution to the equation

example :

let x = 7 then 1/2x - 5/2 = 1/2(7) - 5/2 = 1

in this case  -2x + 4y = -2(7) + 4(1) = -14 + 4 = -10

then (7,1) verify the equation

answer: add the !

step-by-step explanation: then we will answer

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
