Question

Which of the following graphs represents the equation y = 2x + 2?

Answer 1

the answer is the litter B

Answer 2

Answer:

B.) Graph B

Step-by-step explanation:

You can determine which is the correct graph by verifying the points on the graphs with the equation. Remember, the leftmost number in the parentheses is the "x-value" and the rightmost number is the "y-value".

Graph B has the points (0,2) and (2,6) on the line.

y = 2(0) + 2

y = 2

y = 2(2) + 2

y = 4 + 2

y = 6

As you can see, when the "x-values" are plugged into the equation, the value generated matches the "y-value" of the point. Not all the points on the other graphs are accurate according to the equation. You can prove this to yourself by following the same method as above.
