Question

Which ordered pair is a solution to this equation?

y = 2x + 3
A.
(0, 5)
B.
(1, 5)
C.
(2, 6)
D.
(3, -1)

Answer 1

The answer is B

Explanation:

5=2(0)+3

5=3 <---nope

5=2(1)+3

5=5 <---YUP

6=2(2)+3

6=7 <---nope

-1=2(3)+3

-1=9 <--- nope

Answer 2

Hey there! :D

All you need to do is plug in (x,y) points into the equation. For example, the correct answer is "B", plug in the points: 2(1)+3= 2+3= 5

Y= 5 so that works.

You can always make a table and plug in different values for x if you have to find a specific point, especially if the question isn't multiple choice.

I hope this helps!
