Question

Which is a solution to the equation y = 2x – 5?









A.
(2, 1)







B.

(1, –3)








C.
(3, 11)







D.

(5, –5)

Answer 1

r there to equations and u posted one?

Answer 2

Plug in the value for x into the equation and see if you get the corresponding y value when you solve.

Answer 3

Substitute the values given into the equation to see which one gives an equality.
For example:
y=2x-5 (2,1)
1=2(2)-5
1 = 4-5
1 doesn't equal -1 so try the b answer (1,-3)
-3=2(1)-5 solve and see if both sides equal each other

Answer 4

Plug in the answers in the equation:

y = 2x – 5

(2, 1)

1 = 2(2) - 5
1 = 4 - 5
1 = -1

(1, -3)

-3 = 2(1) - 5
-3 = 2 - 5
-3 = -3

(3, 11)

11 = 2(3) - 5
11 = 6 - 5
11 = 1

(5, -5)

-5 = 2(5) - 5
-5 = 10 - 5
-5 = 5

So which is the correct answer?

Answer 5

work it out
