Y = 2x + 50,
It's easier to look at the first set of numbers and then make a formula from there. so we need x to be zero and y to be 50, which is why the formula listed works.
Hopes this can help
<span>Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.</span>
Got my answer of what....

9/4 = 2 1/4

2.25 is your answer
