Answer:
2x + 3y = 10
Explanation:
What we know:
Triangle ABC has Segment AB included in the equation 2x + 3y = 5.
Saying that this is scaled up, Segment A'B' has be included in an addition equation. As a result, Choices 1 and 4 are out. Second, the two terms on the left side have to be the same, so Choice 3 is also out.
This leaves Choice 2, which is 2x + 3y = 10
In case you're confused with the pic below:
eq1's line is 2x + 3y = 5
eq2's line is 2x + 3y = 10
poly1 is the triangle formed on eq1's line
poly2 is the triangle formed on eq2's line
