$\text {x - coordinate = } \bigg( 5\dfrac{1}{2} + 3\dfrac{3}{4} \bigg) \div 2$

$\text {x - coordinate = } \bigg( 5\dfrac{2}{4} + 3\dfrac{3}{4} \bigg) \div 2$

$\text {x - coordinate = } 8\dfrac{5}{4} \div 2$

$\text {x - coordinate = }\dfrac{37}{4} \times \dfrac{1}{2}$

$\text {x - coordinate = }\dfrac{37}{8}$

$\text {x - coordinate = } 4\dfrac{5}{8}$

$\text {y - coordinate = } \bigg( -4\dfrac{1}{4} - 1\dfrac{1}{4} \bigg) \div 2$

$\text {y - coordinate = } -5\dfrac{2}{4} \div 2$

$\text {y - coordinate = } -\dfrac{22}{4} \times \dfrac{1}{2}$

$\text {y - coordinate = } -\dfrac{11}{4}}$

$\text {y - coordinate = } -2\dfrac{3}{4}}$

$\text {The coordinate is }\bigg( 4\dfrac{5}{8}, -2\dfrac{3}{4}} \bigg)$
