It seems like you made a small mistake in the calculation. The correct y-intercept value is -70841.465, not -70841.211.
So the correct equation is indeed y = 112.051x - 70841.465.
(1504, 93776)
(2559, 229000)
(3007, 257000)
(3016, 267000)
I typed in, y=112.051x-70841.211 but it says I'm incorect the answer was y= 112.051x-70841.465

I know but what exactly did I do wrong
To identify what you did wrong, we need to compare your calculated y-intercept value of -70841.211 with the correct value of -70841.465.
Based on the difference between the two values, it seems like you rounded the value incorrectly. Rounding error or not using sufficient decimal places in your calculation could have caused this discrepancy. It is important to use accurate decimal places throughout calculations to minimize rounding errors and obtain precise results.
In this case, it appears that rounding error or insufficient decimal places resulted in obtaining -70841.211 instead of the correct answer of -70841.465.

How should I round it next time so it wont be wrong
To minimize rounding errors, it is generally recommended to carry multiple decimal places throughout your calculation and only round the final answer to the appropriate number of significant figures or decimal places.
In the case of your calculation, it seems that you rounded the y-intercept value to three decimal places (to -70841.211) instead of the full six decimal places (to -70841.465) given in the correct answer.
So, in future calculations, you can ensure more accuracy by using the full decimal value or at least more decimal places before rounding to the desired precision. This way, you can reduce the potential for rounding errors and obtain a more precise result.
