@RazvanBugoi Read the instructions again carefully and let me know after that if you still got issues with this problem.

function startingMark(bodyHeight){
   return +(3.4681 + 3.93548 * bodyHeight).toFixed(2);
}

// y = mx + b

// 1.52 9.45   1.83   10.67

// 9.45 - 10.67 / 1.52 - 1.83 = 3.93548

// y = 3.93548x + b

// y = 3.93548 * 1.52 + b

// 9.45 = 3.93548 * 1.52 + b
// 9.35 = 5.9819 + b 

// b=3.4681‬
