    @dieg Don't just give the answer. Guide @true-love-never-dies through the process.

    If in case you want to learn and not to cheat... To calculate for the length, you have to use the distance formula: \(d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}\) where (x1, y1) = (2, 5) and (x2, y2)= (9, 5) just plug in the given point into the formula. Welcome to Openstudy :)

    Take a look at the points: Points (2, 5) and (9, 5) They have the same Y value. That means it is a horozontal line and you can shortcut this by just seeing the difference in X. So from 2 to 9 is how many steps?

    The calculation AntiNode works in all cases, but yes, on simple ones where either the X or the Y is the same, it is a horozontal or vertical line and it is that easy. So 7 is it.

    I hope that helps the explanation as to why this shorcut works when the y value is the same.
