the easiest way is plug a point into the formula and check I pick (2,0) you put it into EACH of the options and check which one is true
walk me through it please
the option A: \[\dfrac{(x-2)^2}{25}+\dfrac{(y+7)^2}{49}=1\] now , plug (2,0) in, it means x =2, y =0 \[\dfrac{(\color{red}{2}-2)^2}{25}+\dfrac{(\color{red}{0}+7)^2}{49}=1\] \[\dfrac{0}{25}+\dfrac{49}{49}=1\] so, the first option seems good. It's the potential candidate for the correct answer However, you need do the same with other options to make sure you get the correct answer
That's the easiest way to do. I don't want to give you the complicated steps. just do it, you will be fine
